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.
God will appoint salvation for walls and bulwarks. – Isaiah 12:1.
Men appoint walls and bulwarks for salvation; but God appoints salvation for walls and bulwarks. Salvation is often without walls and bulwarks, and walls and bulwarks without salvation. Salvation is the safer safeguard.
