Answer
Insert whatever sins you have committed into the ______. Yes, God can and will forgive any sin. The doctrine of atonement is what explains salvation and forgiveness of sin. God imputed Christ’s righteousness to those who humbly ask for forgiveness of sin (Isaiah 53:5-6; 2 Corinthians 5:21). He paid the full price for our sin, and believers are forgiven fully for every sin they commit—past, present, and future. There is also daily forgiveness as we confess our sins and forsake them for our sanctification. If you compare any sin to the murder of Jesus, it pales in comparison, yet Jesus said, “Father, forgive them for they know not what they do” (Luke 23:34).
The concepts of salvation and forgiveness of sin are inextricably linked. Fortunately, God’s grace is sufficient for any and all sin, whatever sin you put in the blank. Receiving forgiveness of sin is up to the individual. That is the first issue; will you receive the salvation (forgiveness of sin) that Christ is offering? If the answer is "yes," then you are fully forgiven of all debt of sin (Acts 13:38-39). This forgiveness comes by faith in Jesus and God’s grace alone, not by works or good deeds (Romans 3:20,22). Salvation begins by humbly acknowledging that we will never be good enough to get into heaven on our own merit and that we need forgiveness of sin. Accepting Jesus Christ means believing that His death and resurrection paid the penalty for all sin ever committed and that it is sufficient to cover all sin (1 John 2:2).
So, if you have received Jesus Christ as your Savior, God has already forgiven all your sins. If you have not, confess your sins to God, and He will cleanse you and restore you to fellowship with Him (1 John 1:8-9). Even with forgiveness of sin, you may still experience feelings of guilt. Feeling guilty over sin is actually a natural response of our conscience, and it is there to remind us not to repeat sinful patterns. Understanding that Jesus is fully capable of forgiving any measure of sin is the hope of our salvation. Understanding forgiveness is the cure for guilty feelings.
Knowing that forgiveness is really a beautiful, graceful gift from a God who loves us allows us to see how truly wonderful He is. When we contemplate our own sin and how wretched and unworthy of forgiveness we are, it becomes clear that God is loving, compassionate, and worthy of our worship. Our sinful pride that resists asking for forgiveness is what stands between us and a relationship with a caring Savior. But for those who ask for forgiveness of sin, they can believe that Jesus is sufficient and eager to forgive and save them from their sin, and they will ultimately enter into His courts with praise (Psalm 100:4).
