Moses was a man of great faith, and consequently he endured many things at the hands of those who had little or no faith. He was an humble man, "very meek, above all the men which were upon the face of the earth" (Num. 12:3), and by virtue of that meekness he was very probably more a target of Satan's hatred than any other man of his day. But his faith, which God had given him in great measure, enabled him to endure all the trials, discouragements and heartaches that came his way. That faith equipped him to do something very miraculous and wonderful---he could see Him who is invisible to the natural eye. And thus seeing and trusting in the faithfulness and goodness of the Almighty, he pressed forward when lesser men would have fallen by the wayside. 

    Those who have never been visited by the Spirit of God and quickened into Divine life are void of faith and therefore "cannot please God" (See Rom. 8:8 & Heb. 11:6). Not possessing faith, they cannot see Him who is invisible, and in spite of the overwhelming evidence that surrounds them, they do not believe anyone else can either. It makes no sense to the natural mind that anything invisible can be seen. But the apostle Paul shows in Romans 1:30 that they are without excuse, because the invisible things of the Creator, such as His eternal power and Godhead, may be plainly concluded, and known to exist, from the things that He has made, or created. In other words, they ought to know that there cannot be a creation if there is no Creator. The fact that there is a creation clearly shows that there is a Creator. Therefore the Scriptures speak of those as fools who say in their heart, "There is no God" (Psalm 14:1). 

    What a wonderful thing true faith is! It enables us to believe in, rejoice in, love, trust in, and render obedience to, Him whom we have not seen with our natural eyes (See for example I Peter 1:6-9). It enables us to endure many things that otherwise we could not bear. Let us not complain when our faith is tried, for this is one of the primary ways God brings glory to Himself and good to us. It brings joy to our souls and praise to our lips when we endure, "as seeing Him who is invisible."
