Do you have guilt? Do you carry a burden of sin? As a Christian, we will still sin. We fall victim to our flesh. We allow ourselves to become soiled with the filth of this world and we fall. But we do not have to live in the guilt of our sin. If we repent, God tells us that he remove our sin.
When Jesus died on the cross, He made atonement for our sin. John the Baptist makes reference to this when He said, "Behold the Lamb of God which taketh away the sin of the world." – John 1:29. Not only is our sin taken away, but we are given the righteousness of God. "Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed." – 1 Peter 2:24
Now, if we sin all we must do is confess our sin. We must see our sin as God sees it, and turn from it. Then, we will enjoy fellowship with God again. "If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness." 1 John 1:19 Once we have confessed our sin, we do not have to feel guilt. God has removed our sin. Why should we feel as if we must do any more than Christ did.
I would like to encourage you, if you sin, go to God as soon as possible. Confess your sin, ask God to help you, and go right back to serving Him. Once you have done that, you do not have to live in guilt. God has cleansed you.
"Who shall lay any thing to the charge of God’s elect? It is God that justifieth. Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us." – Romans 8:33-34
