That is a biblical pattern. I call it the replacement principle. The Bible is very much concerned with our conduct and one of the tell tale signs of an addict, including a sin addict, is that they don't think it is a big deal, even when it is destroying their lives and the lives of those around them. But sin does matter, sin is why Jesus had to go to the cross!
The call here is to put off the sinful old self (sinful nature, flesh), which lingers with us even after conversion and is characterized by futile thinking and darkened understanding, alienation from God because of ignorance, hardness of heart, callousness, being given over to sensuality, greediness to practice every kind of impurity, and corruption through deceitful desires.
There is the old you, the sinful nature you, and there is the new, born-again you. Both are living in your body still. But to say no to the old self is going to take intentionality. We must be convicted of our sins, which is why even Martin Luther himself, the great proponent of Justification by faith, encouraged his people to read and pray over the 10 commandments everyday. Why? Because conviction is what will lead us to Christ! Those who humble themselves will not have to be humbled, those who accuse themselves will not be accused. Why? Because of the forgiveness that is in Christ, and the renewing and cleansing that we have in the Holy Spirit!
In Prayer Today:
Seek God for the grace of "putting off" the old you, making more room for the new you in the image Christ.
