That is a good question.
That is the most recent post over at Tim Challies blog, ‘Informing the Reforming’

I think the book of Romans answers the question quite well. Start with chapter 6.
What do you think?

The Old Adam Lives! 
Hi Steve! We know that we are “declared” righteous in Christ, and that the demands of the law are paid. But why do we still sin? I think we still sin because we are still here in this old world, still in the “flesh”.
This place is not the place where justice resides – one of the reasons why we are waiting for “a new heaven and a new earth” (2 Peter 3:13). And also, it is written, “he who began a good work in you will bring it to completion at the day of Jesus Christ” (Philippians 1:6) – we are new, and at the same time, He is making us new.
Being in the flesh (not *of* the flesh) is, I think, the reason why we continue to sin. As it is written: “I see *in my members* another law waging war against the law of my mind and making me captive to the law of sin that dwells *in my members*” (Romans 7:23).
We are sinners that are united with Christ, in His death, victory, and resurrection (Romans 6:3-6, Romans 7:25). We are “declared” righteous, and not righteous by our selves. In Christ, we are no longer under the law but “under grace” (Romans 6:14). Since we are not under the law anymore, sin will not have dominion over us because “the power of sin is the law” (1 Cor 15:56).
I have much to say, but my main point is that the Gospel is not a good news apart from the “union with Christ.”
Just some thoughts, Steve. 🙂
Good thoughts, Kebs. That gospel Word has grabbed a hold of you.
Keep up the good work, friend.
St Stephen, For what it is worth a comment was posted for our reformed. Good discussion thanks for pointing it out for me. pacem domine †
