There is a need to seek and put on the new man Ephesians 4:24. This can only come to reality if relying on the grace of our Lord Jesus Christ. To put on the new man, we must accept the Lord Jesus as personal Lord and Savior. When one submits to the lordship of the Lord, the person must make sure to grow in that new encounter so that he or she wouldn't backslide.
When a born-again fellow isn't growing, the old way of life will pop up again. We have a lot of people like that today troubling the Body of Christ due to the fact that they are not growing in grace.
The big question is; are you one of those who believe that the Gospel of Jesus Christ is obsolete and no longer applicable to the 21st century Christian? Are you living your lifestyle without thinking about holiness? You need to repent of your evil ways so that the Adamic nature will give way to a godly way of life anchored on the fear of God.
This creates the start p for growing in grace and living holy. Ephesians 4:24 is a direct command from the Lord.
