I John 1:9

Let us search and try our ways, and turn again to the Lord.

Examine me, O Lord, and prove me; try my reins and my heart.—Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.—I thought on my ways, and turned my feet unto thy testimonies. I made haste and delayed not to keep thy commandments.—Let a man examine himself, and so let him eat of that bread, and drink of that cup.

I acknowledge my transgressions: and my sin is ever before me. Against thee, thee only, have I sinned, and done this evil in thy sight.

And he arose, and came to his father. But when he was yet a great way off, his father saw him, and had compassion, and ran, and fell on his neck, and kissed him.—I have blotted out as a thick cloud, thy transgressions, and, as a cloud, thy sins: return unto me; for I have redeemed thee.—Your sins are forgiven you for his name's sake.—God for Christ's sake hath forgiven you.—That he might be just, and the justifier of him which believeth in Jesus.

Let him take hold of my strength, that he may make peace with me.

I know the thoughts that I think toward you, saith the Lord, thoughts of peace, and not of evil.

Your iniquities have separated between you and your God, your sins have hid his face from you.

My beloved had withdrawn himself, and was gone: . . . I sought him, but I could not find him; I called him, but he gave me no answer.

I will forgive their iniquity, and I will remember their sin no more.—Who can forgive sins but God only?

I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins.—Blessed is he whose transgression is forgiven, whose sin is covered.

The Lord looked down from heaven upon the children of men, to see if there were any that did understand, and seek God.

They are all gone aside, they are all together become filthy: there is none that doeth good, no, not one.—They that are in the flesh cannot please God.

Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly.

If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
