Look unto Me, and be ye saved, all the ends of the earth: for I am God, and there is none else. – Isaiah 45:22

You are to come to Christ to get everything. You are not to say, “Well, I will believe first, and then come.” No; go to Christ for faith. You must look to the cross even to get a sense of sin. We do not feel our sins so much before we see the cross, but we feel them most afterwards. We look to Christ first; then repentance flows from both our streaming eyes. Remember, if you go anywhere else to find a Saviour, you are on the wrong track. If you try to bring anything to Christ, to use a homely proverb, it is like bringing coals to Newcastle. He has plenty-He does not want any of yours, and what is more, as soon as He sees anything in your hands He will turn you straight away. He will have nothing to do with you until you can say-

“Nothing in my hands I bring, simply to Thy cross I cling.”

I have a hundred different phases of this singular fatuity of man-the desire to bring something to Christ. “Oh,” says one “I would come to Christ, but I have been too great a sinner.” Self again, sir; your being a great sinner has nothing to do with that. Christ is a great Saviour; and however great your sin, His mercy is greater than that. He invites you simply as a sinner. Be you big or little, He bids you come to Him and take His salvation “without money and without price.” Another says, “Ah! but I do not feel it enough.” Self again. He does not ask you about your feelings He simply says, “Look unto Me and be ye saved all the ends of the earth.” “But, sir, I cannot pray.” Self again. You are not to be saved by your prayers; you are to be saved by Christ, and your business is simply to look to Christ. He will help you to pray afterwards. You must begin at the right end by clinging only to His cross and trusting there. But, I said to myself, “I will try once more” and I went to the Master, with nothing of my own, casting myself simply on His mercy; and I believed that He died for me…Oh, do try Him.~ C.H. Spurgeon
