Holy Spirit is the third person in Trinity. What is Trinity? Trinity is a Christian doctrine that says, our God is one in three persons. This is a strong doctrine in Christianity. Trinity affirms that we have God the father (John 20: 17), God the son who is the Lord Jesus Christ (Hebrews 1: 8), and God the Holy Spirit (Acts 5: 3-4). These three mentioned persons are one God. Unbelievers (non-Christians alike) find this fact very difficult to understand. Honestly, they cannot be blamed entirely for this, because the Bible says, “……………their foolish heart was darkened” (Romans 1: 21). This Scripture might be the reason for their lack of understanding. Actually, the explanation on the Holy Spirit is beyond any human understanding, it is only the Holy Spirit that can make one to grasp the in-depth and spiritual understanding of the doctrine of Trinity.
However, the three persons of our God should not be mistaken as three Gods. Our God is only one but in three persons. I have already cited above some Bible verses to confirm that these three persons are actually one God. I would also like to cite some Bible passages to drive my point home that our God is actually one in three persons. God the father is a person (Exodus 33: 18-23), but do not get me wrong, our God is not flesh and blood; God the son is also a person (John 1: 1, 14), and God the Holy Spirit is also a person (John 16: 13). Hear what the Scriptures says concerning the personality of the Holy Spirit, “Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself: but whatsoever he shall hear, that shall he speak: and he will shew you things to come” (John 16: 13). It is very obvious to notice how the Lord Jesus Christ describes the Holy Spirit in this quoted Scripture: pronouns “He” and “Himself” that are used for male gender are also used for the Holy Spirit; this is one of the numerous evidences in the Bible to show that the Holy Spirit is a person.
The Holy Spirit is not new to this universe; He has been in operation since the time of creation. The Holy Spirit was in action during the creation of the Heaven and Earth (Genesis 2: 7). All men of God, judges, and prophets of God mentioned in the books of the Old Testament were moved by the Holy Spirit. Listen to what the Bible says concerning this point, “For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost” (2 Peter 1: 21). I would like us to be drawn to an important observation; the Holy Spirit came upon only certain people in the old time as found in the books of the Old Testament. These certain people who were also special people were certainly men of God (Noah, Abraham, Moses, Joshua, King Saul, King David, Daniel, etc) who were loved by God because they walked with Him, prophets (Samuel, Elijah, Elisha, Isaiah, Jeremiah, Ezekiel, etc), or Levites (Jahaziel the son of Zechariah (2 Chronicles 20: 13-17), etc). Another observation concerning these people is that the Holy Spirit came upon them occasionally.
As a matter of fact, the operations of the Holy Spirit in the lives of these special people in the books of the Old Testament are distinctly different from His operations upon the lives of the Christian believers in the books of the New Testament and the Christian believers today.
Firstly, based on the sacrificial death and the precious blood of our Lord Jesus Christ that was shed for our sins coupled with His divine grace upon the life of anyone that believes in Him; the Christians of today are classified as special people before God (1 Peter 2: 9-10). In other words, the Holy Spirit is available for everyone that believes in Christ, He is not for only Pastors, Reverends, Prophets, Sunday School Teachers, Deacons, Deaconesses, etc. We always give thanks to God for this accessibility of the Holy Spirit given to every Christian believer. Hear what the Bible says concerning this, “If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly father give the Holy Spirit to them that ask him?” (Luke 11: 13).
Secondly, the Holy Spirit does not come upon the lives of Christians today occasionally, He lives permanently in us. The Bible says that the Holy Spirit dwells in us (1 Corinthians 3: 16). Our Lord Jesus Christ even buttresses the point by saying that if any Christian keeps His words, He (Jesus), God the father, and the Holy Spirit will come and make their home in the life of such believer permanently (John 14: 23). In addition, luckily for us, our Lord Jesus Christ is the baptizer of the Holy Spirit (Matthew 3: 11). Praise the Lord!
It is noteworthy to mention some of the ministries of the Holy Spirit in the life of a Christian:
1. The Holy Spirit gives strength: Looking at the ministry of the Holy Spirit in giving strength to a Christian, the account of Samson quickly comes to one’s mind (Judges 14: 5-6; 15: 14). As the Holy Spirit manifested His power in the life of Samson in the Old time, He can still do the same in the life of any Christian today, even in a grand style; but it is only when there is a need for that, and the need must be according to God’s purpose. Moreover, the account of Prophet Elijah that outran the chariot of King Ahab when the Holy Spirit was upon him is also a good example of how the Holy Spirit gives strength to Christians (1 Kings 18: 46). In addition, the account of Philip that was caught away by the Holy Spirit, and covered several kilometers of miles is another perfect example of the ministry of the Holy Spirit in giving strength to Christians (Acts 8: 39-40).
2. He brings deliverance: When a Christian is in trouble, the Holy Spirit delivers him both physically and spiritually (Psalm 107: 6). The account of Samson that testified of the Holy Spirit’s deliverance when he was in trouble confirms this point (Judges 15: 18).
3. He makes a Christian to know the heart of God concerning an issue: There are various accounts in the Bible to testify to this fact. An account of how the Holy Spirit came upon a Levite, Jahaziel the son of Zechariah, and he was used as a vessel by the Holy Spirit to tell the whole Israelite congregation the mind of God concerning their problem is a perfect example (2 Chronicles 20: 1-5, 13-17). Another good example of this ministry of the Holy Spirit is an account of how Apostle Peter discovered that Ananias and Sapphira told lie; this is an evidence to show the manifestation of the gifts of the Holy Spirit (Word of wisdom, 1 Corinthians 12: 8) in the life of the Apostle (Acts 5: 1-11). There is no doubt about it, the Holy Spirit has power to make us know the heart of God concerning an issue because the Scriptures says that He (the Holy Spirit) searches all things, even the deep things of God and reveal them unto us (1 Corinthians 2: 10).
4. He brings divine healing power into operation: There are many accounts from the Scriptures which come into one’s mind when it comes to the power of the Holy Spirit in divine healing, but only few of them will be mentioned:
(a) An account of how the Holy Spirit descended upon our Lord Jesus Christ; and he healed the sick people through the power of the Holy Spirit (Mark 1: 9-11, 29-34).
(b) An account of how Apostle Peter healed a lame man at the beautiful gate through the power of the Holy Spirit (Acts 16: 16-18).
(c) An account of how Apostle Paul cast out evil spirit from a woman through the power of the Holy Spirit (Acts 16: 16-18).
Moreover, we should get the idea very clear in our heart that our God is a loving father; one of His ways to demonstrate His love towards Christians is by giving us the promise and power of divine healing through the help of the Holy Spirit (Mark 16: 17-18).
5. He makes Christians capable to do all things: As a result of the power of the Holy Spirit in the life of a Christian, he can boldly say, “I can do all things through Christ which strengtheneth me” (Philippians 4: 13). We should not forget that our boast is not based on our own power or might but on the power of the Holy Spirit who lives in us (Zechariah 4: 6; John 15: 5). By the power of the Holy Spirit there is nothing impossible for Christians.
6. He comforts and guides Christians: The Scriptures says that the Holy Spirit is our comforter (John 14: 16-17). It is not only this, He also guides us (John 14: 26). The Lord Jesus Christ confirms this, “…………..and he will shew you things to come. He shall glorify me: for he shall receive of mine, and shall shew it unto you” (John 16: 13-14).
7. He brings boldness into the lives of Christians: Spirit of fear should not dominate the life of any true Christian, it is because the Bible says, “For God hath not given us the Spirit of fear: but of power, and of love, and of a sound mind” (2 Timothy 1: 7). It is important to understand that the boldness given to us by the power of the Holy Spirit should be used to do the works of God, destroy every manifestation of Satan, and preach the gospel of our Lord Jesus Christ to the entire world (Acts 1: 8). For instance, an account of how Apostle Peter preached the gospel of our Lord Jesus Christ with boldness before the rulers and elders of Israel by the help of the Holy Spirit is a perfect example on the issue (Acts 4: 8-13).
8. He makes Christians to overcome sin: Every true born-again Christian should be able to resist sin in any form the devil may likely use to bring them (Romans 6: 14). This can only happen in a life of a Christian that soaks himself in the word of God, and responds unquestionably to the quickening of the Holy Spirit (1 John 3: 9). We must understand that the Holy Spirit is not a magician; if you are not soaked in the Word of God the Holy Spirit will have nothing to quicken from your heart in order to warn you of any danger of sin. Therefore, it is advisable for us to be rooted and grounded in the Word of God; this will make the operation of the Holy Spirit to be very effective in our lives.
9. He gives utterance to Christians to speak in tongues: The Word of God emphatically declares that without the baptism of the Holy Spirit it will be very difficult for any Christian to speak in tongues (Acts 19: 6). In actual fact, speaking in tongues is the immediate evidence of showing that a Christian is baptized in the Holy Spirit (Acts 2: 4). Speaking in tongues by the power of the Holy Spirit is very important to Christians because it is one of the ways to communicate to God. The Bible tells us that when we pray in tongues we do not speak to men but unto God (1 Corinthians 14: 2). Moreover, when we pray in tongues we allow the Holy Spirit to pray for us as we ought to pray according to the perfect and acceptable will of God (Romans 8: 26-27).
10. He brings hope of eternal life to Christians: The Scriptures says, “If in this life only we have hope in Christ, we are of all men most miserable” (1 Corinthians 15: 19). This is a very serious matter because the Holy Spirit does not stop His operations in our lives when we are no more alive; His operations in the lives of Christians are eternal. No wonder the Bible says that the power (the Holy Spirit) that raised our Lord Jesus Christ from the dead will also raise our own mortal bodies from the dead; this is simply because the same Holy Spirit dwells in us (Romans 8: 11).
We have seen some of the benefits and blessings a Christian enjoys when he is baptized in the Holy Spirit. I believe that it is quite obvious for all to see that the ministries and operations of the Holy Spirit are very essential in the life of a Christian.
