Perhaps a couple of Scripture verses will help with understanding.

 

Colossians 2:10 And ye are complete in him, which is the head of all principality and power:

 

There is no sin in Christ.

 

Colossians 2:11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:

 

Colossians 2:12 Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.

 

Our Spirits are cut away from (circumcised) our flesh.  In the flesh we still have the ability to sin... in the Spirit we do not.  This flesh ins't going to heaven... our vile bodies will be changed and that new body will not sin.

 

While we are in this physical body we have a fight going on to keep it under control.  We won't always be able to do that.

 

Galatians 5:17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.

 

In Christ,
