By faith he left Egypt, not fearing the king's anger; he persevered because he saw him who is invisible. Hebrews 11:27

Moses pleaded with Pharoah a number of times to let his people go. He was hearing from the Lord Himself. After the Lord sent many plagues on Egypt, Pharoah relented and let the Israelites go. It was their one chance at freedom and they weren't turning back. Pharoah's anger burned against Moses and the Israelites, and he hotly pursued them. The pillar guided them by day and the fire by night.

We may not see a pillar or a fire, but we have to listen to what God is telling us. He just may be telling us to draw closer to Him. He may be leading us out of impending danger. He may be showing us to wait in His presence while he showers us with love and encouragement. Or He may be just waiting for us to run to Him any time during the day.

Moses saw "him who was invisible." The "him who is invisible" isn't all that far from us either.
