God Will Forgive Sin. Jesus has the scars to prove it.
1 John 1:9 KJV
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
Matthew 6:14-15 KJV
For if ye forgive men their trespasses, your heavenly Father will also forgive you:  But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
“To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins.”
All too often we consider forgiveness a mysterious and spiritual transaction that, once accomplished, is a past event that has little to do with our subsequent lives.
It is certainly true that there is a historical point in our earthly lives where the forgiveness of Christ was granted, even though He was “slain from the foundation of the world” (Revelation 13:8).
Christ has subdued, cleansed, and forgotten our sins:
“Who is a God like unto thee, that pardoneth iniquity?. . . he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea”
“I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins”
“I have blotted out, as a thick cloud, thy transgressions, and, as a cloud, thy sins”
Christ has replaced our sins with His Righteousness.
“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. . . .
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him”
(2 Corinthians 5:17, 21).
Christ has given us victory over sin: Since all of the above (and more) is true and active in the lives of all believers, there should be an obvious exhilaration that enables us to confidently stand against whatever “fiery darts” the enemy may throw at us.
We are clearly told that “sin shall not have dominion over [us]” (Romans 6:14).
And since Jesus already dealt with the “offence” of sin on the cross, we can “reign in life” by Him
