And Israel saw that great work which the LORD did upon the Egyptians: and the people feared the LORD, and believed the LORD, and his servant Moses. – Exodus 14:31

Do I hear some one say, “I fear that I shall never get out of my difficulties”? Yet you believe that the Lord has brought you out from the dominion of Satan? Tell me, has God brought you so far to let you perish? He has broken off the yoke of sin; He has given you a hope in Christ, and you are a changed man. Do you think that He would do all this for you, and then leave you? Come, my brother, has the Lord brought you out of Egypt, by the precious blood of the Lamb, that you should die in the wilderness? Do you believe that Jesus has redeemed you to let you be lost after all? …Do not doubt Him now, I pray you. Do not please the devil by distrusting your faithful God.

Suppose that the Israelites had been left to perish when Pharaoh said they were shut in, what then? What would the Lord have done for His great name? Would not the Egyptians have exulted over Israel’s God? A Scotch minister tells the story of an aged saint who, on her dying bed, said that her Saviour would never leave her to perish. “But suppose that He did not keep His promise, and you were to be lost?” She answered, “He would be a greater loser than I.” When asked what she meant, she answered, “It is true that I would lose my soul; but God would lose His honor and His glory if He were not true.” Brethren, if we have trusted in God, and have come out of the Egypt of the world through His grace, and have left all its sins behind us, if we were left to die in the wilderness, the Lord Jesus Christ would lose His glory as a Saviour, the divine Father would lose His name for immutable faithfulness, and the Holy Ghost would lose His honor for perseverance in completing every work which He undertakes. ~ C.H.
