In Matthew 26:69-75, Peter denied knowing Jesus three times and wept bitterly when he remembered that Jesus had predicted his betrayal.
After Jesus’ resurrection, however, Christ appeared to the disciples, and Peter was restored. (John 21:15-19)
God can redeem your worst mistakes! You might feel like there is no turning back, but just like Christ redeemed Peter for his worst failure, He can do the same for you.
Psalm 32:1 NIV
Blessed is the one whose transgressions are forgiven, whose sins are covered.
