Romans 6: 1 - 7   
1) What shall we say then? Shall we continue in sin, that grace may abound?
2)  God forbid.  How shall we, that are dead to sin, live any longer therein?
3)  Know ye not, that so many of us as were baptized into Jesus Christ were baptized into Jesus Christ were baptized into his death?
4)  Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5)  For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6)  Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. 


We must stop sinning and continue on in the Lord!


Colossians 3: 9 - 10

I Corinthians 6: 19 - 20
19)  What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
20)  For ye are bought with a price: therefore glorify God in your bodyand in your spiritwhich are God's.
