Separation is the outcome of separation! When a nation (i.e., Israel in the Old Testament) or an individual (i.e., a believer in the New Testament) is set apart by the Lord, that nation (or person) has become disassociated with the rest of the world. Moses made this point in Exodus 33:16 when he said, “For wherein shall it be known here that I and thy people have found grace in thy sight? is it not in that thou goest with us? so shall we be separated, I and thy people, from all the people that are upon the face of the earth.” Separation is not something accomplished through diligence but occurs naturally after a person comes to know Christ as Saviour. Christians who remain attached to the world find little satisfaction with the things of the world or less appeal for the things of God.
At the age of forty, Moses fled Egypt in fear for his life (Exodus 2:11-15; Acts 7:20-29). It is not hard to imagine the degree of fear sensed by Moses as he ran from the most powerful man who ruled the most powerful nation on earth during his day. Today's verse reveals that Moses yet again departed from Egypt, forty years later this time, not fearing the wrath of the king. What made the difference? How did Moses keep from losing his mind during such a difficult time of trial? How did he endure the troubles associated with leaving Egypt? He endured because he saw “him who is invisible.” He saw God! He did not see the Lord simply with his physical eyes, but rather through the eye of faith. Moses endured for one reason, the Lord was with him and he knew it. Endurance becomes possible as the believer learns to acknowledge the presence of the Almighty in his or her life.
