Question: Why do we say “Maker of Heaven and Earth”?
When we consider the creation of God, our faith is strengthened because we know that we do not have a covenant with an unknown God but with a God who daily gives Himself to us to be, so to speak, touched (Acts 17:27,28) and tasted: “Taste and see how good the Lord is; blessed is the man who trusts in Him.” (Psalm 34:8)
26 and He made from one man every nation of mankind to live on all the face of the earth, having determined their appointed times and the boundaries of their habitation, 27 that they would seek God, if perhaps they might grope for Him and find Him, though He is not far from each one of us; 28 for in Him we live and move and exist, as even some of your own poets have said, ‘For we also are His children.’ Acts 17:26-28
Each and every created thing that we use and enjoy daily bears witness to the omnipotence, wisdom, goodness, and mercy of this beloved God. Clear indications of these virtues shine forth in created things, and they will continue to display themselves in the lovely “mirrors” of creation until we leave this misery and see Him as He is in the heavenly fatherland, when we come into His marvelous light, and the glory of the children of God is perfectly revealed in us (Romans 8; 1 John 3).
2 Beloved, now we are children of God, and it has not appeared as yet what we will be. We know that when He appears, we will be like Him, because we will see Him just as He is. 3 And everyone who has this hope fixed on Him purifies himself, just as He is pure. 1 John 3:2, 3
