Peter denied Jesus 3 times! And he is still considered the most loved one among the disciples. Jesus forgave him when he returned, he forgave Paul so rest assured,u is forgiven....No one persecuted Christ more than Saul, (Paul,) did, and he was one of Christ's apostles after he learned the errors of his way. When Christ died on the cross, that brought forgiveness to those that repent. We all fall short, if you are sincere and ask for forgiveness from Him, know that you are forgiven. Too question if there is forgiveness is like re crucifying Christ all over again. That is not good. Accept the fact that Christ died for our sins and we need to repent and ask for His forgiveness. True, those who deny Him and NEVER repent and ask forgiveness will be judged harshly, but you have admitted you were wrong and you need to ask Him in prayer for forgiveness, and ask it in Jesus Christ's name.
