“Eli, Eli, lama sabachthani?” – Matthew 27:46

Now it is easy to believe that God is ours when He smiles upon us, and when we have the sweet fellowship of His love in our hearts; but the point for faith to attend to, is to hold to God when He gives the hard words, when His providence frowns upon thee, and when even His Spirit seems to be withdrawn from thee. Oh! let go every thing, but let not go thy God. If the ship be tossed and ready to sink, and the tempest rages exceedingly, cast out the ingots, let the gold go, throw out the wheat, as Paul’s companions did. Let even necessaries go, but oh! still hold to thy God; give not up thy God; say still, notwithstanding all, “In the teeth of all my feelings, doubts, and suspicions, I hold Him yet; He is my God; I will not let Him go.”

You know that in the text our Lord calls God in the original His “strong one”-“Eli, Eli”-“My strong one, My mighty one.” So let the Christian, when God turns away the brightness of His presence, still believe that all his strength lies in God, and that, moreover, God’s power is on his side. Though it seemed to crush him, yet faith says, “It is a power that will not crush me. If He smite me, what will I do? I will lay hold upon His arm, and He will put strength in me. I will deal with God as Jacob did with the angel. If He wrestle with me, I will borrow strength from Him, and I will wrestle still with Him until I get the blessing from Him.” Beloved, we must neither let go of God, nor let go of our sense of His power to save us. We must hold to our possession of Him, and hold to the belief that He is worth possessing, that He is God all-sufficient, and that He is our God still.~ C.H. Spurgeon
