King David was a man who made many, many mistakes in his life. He sinned greatly before God - even commiting adultery and murder. Yet, throughout his life he always turned toward God with genuine repentance. It was not a repentance of "sorry I got caught/regret"; like, Judas Iscariot (cf. Matthew 27:3). King David's repentance was a repentance of "I hurt You God and I am beside myself with deep, sorrowful grief". David sought for purification. He knew he could not clean himself - he needed God. Interestingly, the Hebrew word for create is the same as in the beginning when God "created the heavens and the earth" (Genesis 1:1). You see, only God can create the universe. In the same way, only God can create a clean heart. David sought a "miracle" from the only being who could give it - God
David was humble before the Lord. He sought a creation of a clean heart. He sought a pure soul.
God does this "miracle" for all people who are His. He creates in them a "clean heart". If anyone seeks a miracle, it should be this one.
