Paul is telling us not to live like ignorant and unconverted people do. They have not been regenerated and their minds are full of darkness. They do not walk in the light of the truth of the Gospel. Why? Because they have refused to heed the call of God’s Spirit and have refused to be obedient, so their hearts and minds are closed to any move by the Spirit. Therefore, they live only to satisfy the lusts of the flesh and they participate in all kinds of sinful activity. But we know better. Why? Because we have heard and accepted the Truth. So, we walk according to God’s Spirit. That means that we stop our sinful ways that were corrupted by lust and deception. We are now a new creature and we are guided by the Spirit of God. The real “us” that is carried around in these tents of flesh is being made into God’s image. We look forward to the day when we shall see Jesus. At that time, we will be totally converted into His image. “What a wonderful change in my heart has been wrought’ I’ve been washed by the blood of the Lamb.” Hallelujah and Amen!
