I see that YOU really need to be careful...
Rom 6:9 For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him.
Rom 6:10 The death he died, he died to sin once for all; but the life he lives, he lives to God.
Rom 6:11 In the same way, count yourselves dead to sin but alive to God in Christ Jesus.
Rom 6:12 Therefore do not let sin reign in your mortal body so that you obey its evil desires.
Rom 6:13 Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life; and offer the parts of your body to him as instruments of righteousness.
Rom 6:14 For sin shall not be your master, because you are not under law, but under grace.
Rom 6:15 What then? Shall we sin because we are not under law but under grace? By no means!
Rom 6:16 Don’t you know that when you offer yourselves to someone to obey him as slaves, you are slaves to the one whom you obey—whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness?
Rom 6:17 But thanks be to God that, though you used to be slaves to sin, you wholeheartedly obeyed the form of teaching to which you were entrusted.
Rom 6:18 You have been set free from sin and have become slaves to righteousness.
We are to count ourselves dead to sin but that doesn't mean we are free from sin. Paul also stated:
Paul knew very well that we as Christians serve the law of sin.
Quite frankly I find Christians who state that they are not subject to sin or do not have sin quite puzzling. I only have to look inside my heart to see corruption. It refreshes me to know that God is taking care of "the mess in the attic" but I'm also well aware of my own inadequacies. As Paul states, thanks be to God that we can serve the law of God because of Christ. All one has to do is look inside themselves to see their own corruption. And that's the very heart of what being a Christian is all about.
