from Ephesians 3
""The word translated manifold here is literally the “many-colored wisdom of God.” Why did the apostle choose this poetic adjective? It is because life consists of many colors. We all have blue days. And red hours of anger and passion. And golden moments of glory. And dark, somber valleys through which we must pass. And lush, green pastures into which we are sometimes led. God's love is manifest in all of these hues of life. So when you go through a blue time, it is God's love that you are learning. When you go through a dark and pressured time, the love of God is being manifested there. You may not see it, but God knows how to make it clear. And even the joyful times are manifestations of the many-colored wisdom of God.
And as the angels watch us, they see us learn to trust God, to turn from our fears and to renew ourselves with divine strength, to draw upon God's great and mighty promises in the hour of pressure and danger. As they see this, their praise begins to ring out in amazement and wonder at a God—who is also able to find a way by which He can lavish His love upon the very ones who deserve His wrath. This makes the angels praise God.""
