Ecclesiastes "He has made everything beautiful [perfect] in its [His] time. He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end." God is Time in Himself!
Above all else, guard your heart, for everything you do flows from it. What is in our hearts comes out through our words and actions. We must guard our hearts from evil so that we can abstain from doing evil.
