Ephesians 4:22-24 – You were taught with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your mind; and to put on the new self, created to be like God in true righteousness and holiness.
When we receive salvation we are made new, but to live that new life sometimes it takes some effort. We often have old habits and things we used to do that are no longer what we ought to be doing. It is time to put off our old selves.
Our old self is full of selfish desires, because before Christ we were living for ourselves. That is what needs to change. It’s not always the action itself, but the motivation behind it. The old self was corrupt. Everything you did was corrupt. Not because it was necessarily bad, but because it corrupted by your deceitful heart.
Now our hearts are made new and we have to line up our thinking with our new way of life. Paul says it like this, “be made new in the attitude of your mind.” Our way of thinking has to change. Romans says “do not conform any longer, but be transformed by the renewing of your mind.” Your new self is made to be like God in true righteousness and holiness, so start living like it.
Our old habits can return us to our old way of thinking, so if you see that happening, get rid of them. Cast them off. Live your new life. Take hold of what Christ has done for you by renewing your mind with God’s Word.
