Jesus said, “No one can see the kingdom of God unless they are born again.” This new birth is heaven's makeover of the heart and soul. However, many professing Christians today have never been born again. They have varying degrees of outward morality and religion. But, they've never undergone that great change of heart.
So what is the new birth? From the human side, it is the decision to change my heart and mind from an attitude of hostility towards God to one of love and obedience. From God's side, it is the renewing of the soul, mind, and heart from death to life. As a result, the heart is pure instead of evil, and the soul is thus fit to enter the kingdom of God.
Are you born again, with continued evidence of that fact?
