Sin is a selfish decision to do it your own way. Guilt is the thief of faith. When you permit sin in your life, you become uncomfortable in the presence of God.
It is difficult to expect a miracle from a God you resent. Confess your failure. God forgives. Repentance is a decision to make unselfish choices doing it God’s way.
“If I regard iniquity in my heart, the Lord will not hear me:”
(Psalms 66:18)
