THE UNREGENERATE MIND IS DECEIPTFUL AND CORRUPT AND WHO COULD KNOW IT

Col 3:9-10
9 Do not lie to one another, for you have stripped off the old (unregenerate) self with its evil practices,
10 And have clothed yourselves with the new [spiritual self], which is [ever in the process of being] renewed and remolded into [fuller and more perfect knowledge upon] knowledge after the image (the likeness) of Him Who created it. [Gen 1:26.]
