Here is what I taught in Water of Life Christian Training School (beginning in September 1983 through May 1990) concerning forgiveness of sins.
12 Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light: 13 Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: 14 In whom we have redemption through his blood, even the forgiveness of sins:
I John 1
7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. The light is the gospel, the death, burial, and resurrection of Jesus Christ. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.
If you will obey these verses from I John 1:7-10 here is what will happen to your sins.
As far as the east is from the west, so far hath he removed our transgressions from us.
18 Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever, because he delighteth in mercy. 19 He will turn again, he will have compassion upon us; he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea. 20 Thou wilt perform the truth to Jacob, and the mercy to Abraham
For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
And their sins and iniquities will I remember no more.
31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah: 32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord: 33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people. 34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
If the Lord remembers your sins and iniquities no more neither will you, when they are forgiven and purged from your conscience to serve the living God.
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
These dead works happen to be your works of sin. Then you will be justified, just as if you had never committed the sin.
25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
I am praying for you that all this will be accomplished in you,
1 For I would that ye knew what great conflict I have for you, and for them at Laodicea, and for as many as have not seen my face in the flesh; 2 That their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgement of the mystery of God, and of the Father, and of Christ; 3 In whom are hid all the treasures of wisdom and knowledge. 4 And this I say, lest any man should beguile you with enticing words. 5 For though I be absent in the flesh, yet am I with you in the spirit, joying and beholding your order, and the stedfastness of your faith in Christ. 6 As ye have therefore received Christ Jesus the Lord, so walk ye in him: 7 Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving.
Servant and apostle of the Lord Jesus Christ
