Is it true that if we do not forgive people their sins, they will not be forgiven (John 20:23)?

Is it true that if we do not forgive people their sins, they will not be forgiven (John 20:23)?
Redemption The Bible New Testament

TL;DR:

Only God can forgive sins, but we can declare what God has promised: those who trust in Christ are forgiven and those who reject Him remain in their sins. John 20:23 is not about believers controlling forgiveness—it is about proclaiming the gospel, which reveals who has received God's forgiveness and who has not.

from the old testament

  • Although this exact topic is not covered in the Old Testament, we do have the example of David's confession in Psalm 32:5,  "I acknowledged my sin to you, and I did not cover my iniquity; I said, 'I will confess my transgressions to the LORD,' and you forgave the iniquity of my sin. Selah"
  • Psalm 51:4 tells us that in regards to David's sin with Bathsheba, his sin was ultimately against God. This implies that all sin is against God.

from the new testament

  • “Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on him” (John 3:36).
  • John 8:24 says, “If you do not believe that I am [God], you will indeed die in your sins.” This tells us that your sins will not be forgiven unless your trust is in Christ.
  • In Matthew 6:14-15 Jesus told His disciples, "For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses."
  • Jesus expects us to forgive others and especially our fellow believers (Matthew 18:22; Colossians 3:13; 1 John 2:3-6).
  • Romans 3:23 tells us that we are sinners and have all fallen short of God's glory.

implications for today

Since only God forgives sins, the disciples were not the ultimate source of forgiveness; however, they were the ones who could declare that sins were forgiven or not. This forgiveness is based only on the person's belief in Christ's sacrifice on the cross. Although we as followers of Jesus are able to forgive someone of their personal sins against us, we do not have the power to forgive sins against God. But we do have the ability to confirm a person's forgiveness based upon their confession of faith.

Our role is not to sit in the place of God deciding who is ultimately forgiven but to faithfully point people to the only One who can forgive sin. Real forgiveness doesn’t come from us. It comes from God through Christ, and it is received by those who turn to Him in faith. That means when we speak about forgiveness, we are not controlling people’s eternal standing, but clearly declaring what God has already said is true: those who trust in Christ are forgiven, and those who reject Him remain in their sin. This gives our words real weight because we are either helping people see the way into forgiveness or warning them about the seriousness of remaining apart from it.

At the same time, we are still called to forgive personal wrongs against us, refusing to carry bitterness or repay harm with harm. Holding onto unforgiveness in our relationships contradicts the very mercy we have received and keeps our hearts tied to the very things God has freed us from. Living this way keeps us humble and focused, aware that we are not the source of forgiveness but that we have been entrusted with pointing others to it.

understand

  • Since all sin is against God, only God is the ultimate source of forgiveness.
  • When Jesus told the disciples they could forgive or not forgive, it was based upon the person's faith in Christ.
  • Today, we can also tell people they are forgiven or declare their sins are not forgiven if they don't believe.

reflect

  • How do you know if your sins are forgiven?
  • How does knowing that only God can ultimately forgive your sins change the way you view your own standing before Him today?
  • How are you pointing people to the gospel message and the forgiveness available to those who trust in Christ?

engage

  • How can we help others understand that we are not the ultimate source of forgiveness, and that only God forgives?
  • Upon what basis can we tell someone their sins against God are forgiven or not forgiven?
  • What does it look like in everyday life for us to faithfully declare truth about forgiveness without placing ourselves in God’s role?
