Thinking, praying, reading, studying the Bible – when we do these things, we are reflecting on the Word of God. To reflect is to contemplate and/or consider, and God wants us to deeply reflect on His Word so that we can better understand Him.
What will you do in the end? – Jeremiah 5:31.
Better it is, toward the right conduct of life, to consider what will be the end of a thing, than what is the beginning of it; for what promises fair at first may prove ill, and what seems at first a disadvantage, may prove very advantageous.
