In Ephesians 4:17-24, Paul reminds the believers of not sliding back into their old lives. Using words like futile, darkened, excluded and more, Paul paints a picture of what life was like prior to them receiving Christ. But then he contrasts that old life with the new life they have in Christ.  Sliding back into our pre-Christian life is not as uncommon as you may think and in fact you yourself may have made many, many trips there. Paul asks the believers to put off that old life and to put on the new life we have in Christ. We do that by being renewed in our minds day by day. God’s word, prayer, meeting together with other Christians, worship and so many other things all aid us in being renewed and learning Christ.
