Do I need to confess my sin of lust before taking communion?

Answer:

What you are describing could fall under the category of sexual touching if you were touching your boyfriend to arouse sexual desire in you or him. "Now concerning the things about which you wrote, it is good for a man not to touch a woman" (I Corinthians 7:1). Lust is a state of mind where you think about doing sinful things and justify it to yourself. Lust often proceeds the committing of sin (Mark 7:21-23).

When a Christian realizes he has sinned, he is required to make changes in his attitude and behavior. This is what is called repentance. "For the sorrow that is according to the will of God produces a repentance without regret, leading to salvation, but the sorrow of the world produces death. For behold what earnestness this very thing, this godly sorrow, has produced in you: what vindication of yourselves, what indignation, what fear, what longing, what zeal, what avenging of wrong! In everything you demonstrated yourselves to be innocent in the matter" (II Corinthians 7:10-11).

God also requires that you admit your sin to Him. "If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness" (I John 1:9).

There is no requirement that those who partake of the Lord's Supper be sinless. People often misread what Paul wrote: "Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord" (I Corinthians 11:27). Paul said the manner in which the Lord's Supper must be done in a way that is worthy of the sacrifice that Jesus made on our behalf. He did not say we must be worthy because no man is worthy of the love Jesus showed for us. In other words, the Lord's Supper is to be conducted in a solemn and respectful manner as we remember Jesus' death on our behalf.
