Create in me a clean heart, O God, And renew a steadfast spirit within me. Do not cast me away from Your presence, And do not take Your Holy Spirit from me. (Psa 51:10-11 NKJ)
We started out with a cry for mercy and compassion after being truly repentant for sin, but now David looks to the future, as we should also. David’s request is for a clean heart; God responds by giving us a new heart. Look at these three scriptures:
Ezekiel 36:26–And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh.
2 Corinthians 5:17–Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.
Romans 12:2–Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
A new heart, and the potential for a new life, and a new future, so, as Paul tells us then, don’t be conformed to the world. In other words, no let the old nature take you back to the old you, but keep on moving forward, being transformed by the power of God.
