How will we be freed from the indwelling of sin?

When Jesus comes, we will receive new bodies free from the presence of sin. So we will be glorified in Christ.

Php 3:20-21

For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself.
