“Do not lie to each other, since you have taken off your old self with its practices, and have put on the new self, which is being renewed in knowledge in the image of its Creator.” Colossians 3:9-10 (NIV)
Paul writes to the faithful believers at Colosse. He admonishes the brothers and sisters not to lie to one another, giving them a reason to refrain from deception. They have removed the old self with its evil, conceited ways and have replaced it with a new self. The Holy Spirit renews that new self each day.
In looking at this passage, I notice that the Holy Spirit works to renew us as we approach Jesus in prayer, ask His forgiveness for, and repent from our falling short of what He has planned for us.
This renewal of self may be instantaneous. We sense a lightening of our spirit. Our burden is lifted and our hearts are free. Or we continue our daily lives but notice events appear affect us differently, we respond to those scenes more gently. We finally realize that God had performed what we have asked Him.
Because we have abandoned our old self and allowed Christ to remake our personas, we will resemble Jesus to others.
