God's promises define what is real according to God's power, God's plan and God's purposes. When you are overwhelmed by the Egypt times or the wilderness times or the Jericho times in your life it is easy to believe what you feel instead of what you know. When you lose touch with God's reality what you feel becomes what is real. Under pain and pressure you will tend to believe what you SEE not what God SAYS!
If you are to arrive in the Promised Land in your journey out of Egypt and through the wilderness and into Canaan you will have to be focused on the reality of God's eternal promises not the emotions of daily pressures and pain.
Whatever you are battling today, let the promises of God define your reality! Believe what He says not what you see!
