According to Ephesians 1:4-5, God, “Chose us in Him before the foundation of the world.” God has predestined Christians to be adopted as His own children through His Son Jesus Christ. He does this, “because of His great love” (Ephesians 2:4) and so, “He might show the surpassing riches of His grace” (Ephesians 2:7). Also, the Bible is explicit that Christians have done nothing to earn this salvation, it’s purely a gift of God (Ephesians 2:8-9) and God prepared all of this in advance (Ephesians 2:10). God not only predestined the salvation of Christians, but the good works that would be done by them (Ephesians 2:10) which reveals how God not only gives initial salvation, but remains active in the believer’s life, changing and transforming them from the inside out. To say all of this could be lost, or thrown away, would be the equivalent of saying God must not have chosen the right people, or maybe His plan for their life failed, but of course neither of these options are possible for God because He always completes what He begins (Romans 11:29)(John 6:37-39).
If the Bible makes it abundantly clear that receiving salvation is not about the receiver, but about God’s abundant grace, it should be just as clear that keeping salvation is neither about the receiver. Although the Bible continually urges Christians to persevere in their faith, the assumption should not be made that that perseverance is solely on the shoulders of the believer, especially since the Bible states it is not. Hebrews 12:2 says it is Jesus who is not only the author of faith but also the perfecter, and Philippians 2:13 says, “it is God who is at work in you, both to will and to work for His good pleasure.” Jesus is said to constantly be interceding for His saints (Hebrews 7:25) and through Him they have an advocate with the Father (I John 2:1). The same God who calls and saves His children will also fully establish them (1 Peter 5:10).
God wants Christians to be confident in their salvation and to not live in fear of losing it, so much so that He sends His Holy Spirit to take up residence in their heart and is given as a guarantee, a pledge, or a deposit of their salvation, and His Spirit “seals” them in Christ (Ephesians 1:13-14). A deposit is a partial payment given to guarantee the full payment is coming. The Holy Spirit is God’s deposit as a guarantee to all who are in Christ, it guarantees He will keep His promises and bring His children through this temporary life and on to eternity with Him forever, (Romans 8:16-17) just as the Apostle Paul claimed in 2 Timothy 4:18. Although believers receive the Holy Spirit the minute they believe and trust in Christ’s atoning work, (Romans 8:9) the full consummation of their redemption will only be achieved when Jesus receives full possession of His own. The seal of the Spirit in the Christian signifies they belong to God and He has authority over their life.
Having shown how God sovereignly and freely gives salvation “before the creation of the world,” and aides the Christian in living out that salvation by working in them and sealing them with the guarantee of the Holy Spirit, the Bible continues this promise all the way to the very end in the book of Revelation.
In Revelation 3:5, and other places in scripture, there is something written about called “The book of Life,” which is a figurative name of a sort of record God keeps of Christ followers (Luke 10:20) (Philippians 4:3). In Revelation 13:8 the Bible tells us the names of these believers have been “written from the foundation of the world,” which gives Christians every reason to believe and rejoice that God, who called and saved them, will bring them safely into His presence for all of eternity (Romans 8:29-30) and nothing will be able to separate them from the love of God which is in Christ Jesus the Lord (Romans 8:37-39).
