God wants us to live righteously, but how can we practice righteousness when, by nature, we're sinful people? And how can anything we do be considered righteous since all aspects of our lives have been tainted by sin? Our God is pure and far above everything He has created, but still His righteousness is made available to us, and in blessing us with it, He remedies this dilemma.
Let's consider God's capacity for just a moment. He's not only "high capacity", He's "infinite capacity." He never sleeps or slumbers. He is perfect in all His abilities. There isn't a single thing that He doesn't know, and there is no one more powerful than Him. And unlike humans who can only be in one place at one time, He is everywhere at the same time. This is amazing, and just like the Psalmist said in Psalm 113, "Who is like the Lord our God?" The answer, very simply, is no one.
