God does not create something, and then abandon it. No, he sees things through until completion. That includes the world he created, but also his work in us. Paul said in his letter to the Philippians (vs. 6), “being confident of this, that he who began a good work in you will carry it on to completion…” And, as the old Sunday School song says,
He's still working on me to make me what I ought to be.
It took Him just a week to make the moon and stars,
The sun and the earth and Jupiter and Mars.
How loving and patient He must be, He's still working on me.
What a great God!
