"If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness"(1 Jn 1:8-9)

"Say to the people of Israel, When a man or woman commits any of the sins that men commit by breaking faith with the Lord, and that person is guilty, 7 he shall confess his sin which he has committed; and he shall make full restitution for his wrong, adding a fifth to it, and giving it to him to whom he did the wrong." (Num 5:6-7 )

"I acknowledged my sin to thee, and I did not hide my iniquity; I said, 'I will confess my transgressions to the Lord'; then thou didst forgive the guilt of my sin. "(Psalm 32:5)

"On the way to Jerusalem he was passing along between Samaria and Galilee. And as he entered a village, he was met by ten lepers, who stood at a distance and lifted up their voices and said, "Jesus, Master, have mercy on us." When he saw them he said to them, "Go and show yourselves to the priests." And as they went they were cleansed." (Lk 17:11-14 )

"And have you forgotten the exhortation which addresses you as sons? -- 'My son, do not regard lightly the discipline of the Lord, nor lose courage when you are punished by him. For the Lord disciplines him whom he loves, and chastises every son whom he receives.' It is for discipline that you have to endure. God is treating you as sons; for what son is there whom his father does not discipline? If you are left without discipline, in which all have participated, then you are illegitimate children and not sons. Besides this, we have had earthly fathers to discipline us and we respected them. Shall we not much more be subject to the Father of spirits and live? For they disciplined us for a short time at their pleasure, but he disciplines us for our good, that we may share his holiness. For the moment all discipline seems painful rather than pleasant; later it yields the peaceful fruit of righteousness to those who have been trained by it. Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed" (Heb. 12:5-13)

"Jesus said to them again, "Peace be with you. As the Father has sent me, even so I send you." And when he had said this, he breathed on them, and said to them, "Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained." (Jn 20:21-23)

"Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven." (Mt 18:18)

"Therefore, holy brethren, who share in a heavenly call, consider Jesus, the apostle and high priest of our confession" (Heb 3:1 )

Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him. Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much." (James 5:14-16)

"And Simon answered, "Pray for me to the Lord, that nothing of what you have said may come upon me." (Acts 8:24))

"All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; 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. So we are ambassadors for Christ, God making his appeal through us. We beseech you on behalf of Christ, be reconciled to God." (2 Cor 5:18-20)

"Any one whom you forgive, I also forgive. What I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ,... " (2 Cor 2:10 )
