ISN'T THAT FORGIVENESS?

Do we believe that we must "FORGIVE OURSELVES" in order to have the "Fullness of CHRIST"?  Can we Forgive our selves of our sin?  "...not that man can Forgive sins, that belongs only to GOD...(ISAIAH 43:23).   Is Forgiveness really confirming all that JESUS taught and our actions are the result of living in HIS LOVE?  JESUS set us free of the Bondage of sin, so why can't we "remember no more"?    It is because we choose to remember sin because we want to relive those sins, thus we continue to commit those sins over and over.  When we live in the presence of GOD, we think, pray and reJOYce IN HIS LOVE.  When our hearts constantly think about HIM, we no longer "dwell in our sins" and the sins of others.   Only then do we "REMEMBER NO MORE".  ISN'T THAT FORGIVENESS?
