One work of faith is to believe that God still loves you after you fall into sin:
Luke 22:31-32 And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat:
But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren.
Satan deceives many people and false christians alike that "since God loves you, it is ok to sin". But for the true Christians, he condemns them that "God does not love you anymore because you sin". Don't listen to the Devil.
God loves you, confess your sin to God even if others don't consider it a sin. God will forgive you and not only that, he will also cleanse you from all unrighteousness! (1 John 1:9)
Matthew 18:21-22 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?
Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
God does not command us to do something that He himself does not do. He is faithful.
