We had better hope God can forgive future sins because Jesus died over 2,000 years ago, long before we ever sinned.
In the Old Testament, when they sacrificed a lamb, it was for sins already committed. So, does that mean that none of our sins are forgiven? I say that because Jesus sacrifice was over two thousand years ago, long before we ever sinned. So how can Jesus sacrifice cover sins that have not been committed yet, sins far in the future from when He was crucified?
God lives outside of time.
The Bible is quite clear that Jesus died once for all sins for all time, the entire span of time. Once a person believes the gospel, all of their sins are forgiven.
For by one offering He has perfected for all time those who are sanctified. Heb 10:14
Here is a more in-depth explanation.
1) God created time but is not bound by time. The Creator is set apart from the creation. The word "Holy" means set apart.
We know from the scientific evidence that time had a beginning with the creation of the universe. Long before science discovered time had a beginning, the word of God told us time had a beginning. So, time is a bubble God created but does not live in like us. Time binds the enemy, sin, and death too.
He has saved us and called us to a holy life--not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time, 2 Tim 1:9 NIV
in the hope of eternal life, which God, who does not lie, promised before the beginning of time, Titus 1:2 NIV
Who has done such mighty deeds, summoning each new generation from the beginning of time? It is I, the LORD, the First and the Last. I alone am he." Isa 41:4
2) God does not live in time, like His creation. Time is part of the creation.
For a thousand years in Your sight Are like yesterday when it passes by, Or as a watch in the night. Psalm 90:4 NAS
But do not let this one fact escape your notice, beloved, that with the Lord one day is like a thousand years, and a thousand years like one day. 2 Peter 3:8 NAS
3) God is eternal having no beginning or end as time does. Only things that come into existence are bound by time.
But You, O LORD, abide forever, And Your name to all generations. Psalm 102:12 NAS
I say, “O my God, do not take me away in the midst of my days, Your years are throughout all generations. “Of old You founded the earth, And the heavens are the work of Your hands. “Even they will perish, but You endure; And all of them will wear out like a garment; Like clothing You will change them and they will be changed. “But You are the same, And Your years will not come to an end. Psalm 102:24-27 NAS
God said to Moses, "I AM WHO I AM"; and He said, "Thus you shall say to the sons of Israel, 'I AM has sent me to you.'" Exd 3:14 NAS (I AM is the self-existent, eternal one.)
4) God sees the end from the beginning.
Declaring the end from the beginning, And from ancient times things which have not been done, Saying, 'My purpose will be established, And I will accomplish all My good pleasure'; Isa 46:10 NAS
"Who has performed and accomplished it, Calling forth the generations from the beginning? 'I, the LORD, am the first, and with the last. I am He.'" Isa 41:4 NAS
"I am the Alpha and the Omega," says the Lord God, "who is and who was and who is to come, the Almighty." Rev 1:8 NAS (Alpha and Omega is the beginning and the end.)
"I am the Alpha and the Omega, the first and the last, the beginning and the end." Rev 22:13 NAS
5)The Bible points out that Jesus was slain from the foundation of the earth.
And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. Rev 13:8 KJV
It also states Jesus appeared at the end of the age to put away sin by the sacrifice of himself.
for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself. Heb 9:26 ESV
That looks like Jesus sacrificed himself twice.
But this gets even better because to us it looks like there is a third time in 33ad. That looks more like the middle of the age. So, from what we read it appears that Jesus sacrificed himself three times. Before the foundation of the world, in 33ad and at the end of the ages.
6) But the Bible tells us clearly that Jesus sacrificed himself only one time for all sins, for all time, not three times.
By this will we have been sanctified through the offering of the body of Jesus Christ once for all. Heb 10:10 NAS
For it was fitting for us to have such a high priest, holy, innocent, undefiled, separated from sinners and exalted above the heavens; who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because this He did once for all when He offered up Himself. Heb 7:26-27 NAS
7) How is it possible Jesus only had to die once for all sins?
What God does outside of time applies to all time. Hebrews 10:14 tells us Jesus one sacrifice covered all sins, for all time. The entire span of time from the beginning to the end.
8) There will be an end of time for us too when we will no longer be bound by time. No aging and no more death, young always, eternal life in Christ.
Then he said, "I am here to tell you what will happen later in the time of wrath. What you have seen pertains to the very end of time. Dan 8:19 NAS
"But as for you, Daniel, conceal these words and seal up the book until the end of time; many will go back and forth, and knowledge will increase." Dan 12:4 NAS
"And you, Daniel, be faithful to the end. Then you will die, but you will rise to receive your reward at the end of time." Dan 12:13 GNT
9) This is something to be very excited about, Christian. Your past, present, and future sins have been forgiven in Christ’s one sacrifice for all, for all time. You have been forgiven much! This absolute truth believed will cause you to love much.
"For this reason I say to you, her sins, which are many, have been forgiven, for she loved much; but he who is forgiven little, loves little." Luke 7:47 NAS
Failure to believe this truth is what keeps the fruits of the Spirit from growing in your life. The fruits of the Spirit replace the acts of sin once you firmly believe how much God loves you and that you are forgiven for all time. Read: What is The One Thing That Keeps a Believer in Sin?
10) This is how God gets us to fulfill the intent of His written laws. Love is what fulfills the Spirit of all of God’s written laws. The Spirit of a written law is the authors original intent for writing the law. It is the only thing that can truly fulfill the letter of the law and the author's desire.
Owe nothing to anyone except to love one another; for he who loves his neighbor has fulfilled the law. For this, “YOU SHALL NOT COMMIT ADULTERY, YOU SHALL NOT MURDER, YOU SHALL NOT STEAL, YOU SHALL NOT COVET,” and if there is any other commandment, it is summed up in this saying, “YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.” Love does no wrong to a neighbor; therefore love is the fulfillment of the law. Rom 13:8-10 NAS
For the whole Law is fulfilled in one word, in the statement, "YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF." Gal 5:14 NAS
11) When the Bible says, you are qualified to be a minister of the Spirit that gives life and not the letter that brings death; It is saying you are qualified to minister the Spirit of the law which is love, not the letter of the law that brings death. The letter of the law can only tell you what not to do; it cannot tell you to give $500.00 to your friend in need. The letter will never tell you it is okay to miss church because you saw a person in need and stopped to help them, but the Spirit will tell you this is okay. Listen to the Spirit.
The story of the good Samaritan, the woman caught in adultery, the woman with blood, Jesus numerous healings on the Sabbath and many more are all examples where the letter of the law was not kept but the Spirit of the law was. Jesus life is an example of walking in the Spirit of the law. In the Old Testament, it was an eye for and eye and a tooth for a tooth. With Jesus, it is love your enemy as I have loved you.
who also made us adequate as servants of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. 2 Cor 2:6 NAS
12)But it gets even better, Christian. In the New Covenant, Jesus shed His blood for – Luke 22:20, God has placed you under grace where your sins are not even being counted. Under grace, sin has no dominion over you and cannot take your life.
For sin shall not be master over you, for you are not under law but under grace. Rom 6:14 NAS
"I will forgive their iniquity, I will remember their sin no more.” Jer 31:34b
“…that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation” (2 Cor 5:19).
“For the law brings wrath, but where there is no law there is no transgression” (Rom 4:15).
...For apart from the law, sin lies dead (Rom 7:8).
...“I will remember their sins and their lawless deeds no more.” Heb 10:17

Many more New Covenant Bible Studies HERE. Jesus poured out His blood for the New Covenant of grace and truth, replacing the Old Covenant law of Moses. Believers are exclusively under the New Covenant, the last will and testament of Jesus that began after the cross.
And in the same way He took the cup after they had eaten, saying, "This cup which is poured out for you is the new covenant in My blood. Luke 22:20
