And when they had lifted up their eyes, they saw no man, save Jesus only. – Matthew 17:8

If I want to know whether a certain estate is mine, do I look into my own heart to see if I have a right to it? But I look into the archives of the estate, I search testaments and covenants. Now, Christ Jesus is God’s covenant with the people, a leader and commander to the people. To-day, I personally can read my title clear to heaven, and shall I tell you how I read it? Not because I feel all I wish to feel, nor because I am what I hope I yet shall be, but I read in the word that “Jesus Christ came into the world to save sinners,” I am a sinner, even the devil cannot tell me I am not. O precious Saviour, then thou hast come to save such as I am. Then I see it written again, “He that believeth and is baptized, shall be saved.” I have believed, and have been baptized; I know I trust alone in Jesus, and that is believing. As surely then as there is a God in heaven, I shall be in heaven one day. It must be so, because he that believeth must be saved. You see it is not by looking within, it is by looking to Jesus only that you perceive at last your name graven on His hands. I wish to have Christ’s name written on my heart, but if I want assurance, I have to look at His heart till I see my name written there. O turn your eye away from your sin and your emptiness to His righteousness and His fullness. See the sweat drops bloody as they fall in Gethsemane, see His heart pierced and pouring out blood and water for the sins of men upon Calvary! There is life in a look at Him! O look to Him, and though it be Jesus only, though Moses should condemn you, and Elias should alarm you, yet “Jesus only” shall be enough to comfort and enough to save you. May God grant us grace every one of us to take for our motto in life, for our hope in death, and for our joy in eternity, “Jesus only.” May God bless you for the sake of “Jesus only.” Amen. ~ C.H.
