Now consider how great this man was… – Hebrews 7:4

Count every minute wasted in which you are not learning more about Jesus. Reckon all other knowledge to be as mere chaff and dog’s meat as compared with the knowledge of Christ crucified. In these days of science, falsely so called, determine with the apostle to know nothing among men save Jesus Christ and Him crucified. It is imperative upon you that you love the Lord your God with all your heart, and all your soul, and all your mind; and that God in Christ Jesus should call into exercise every faculty of your inner man, while, with blended intellect and emotion, you consider how great He was.

Here is a rock beneath my feet-“God was in Christ, reconciling the world unto Himself, not imputing their trespasses unto them.” Certain great facts concerning God and His Christ have been made known to us by the Holy Ghost, and these are infallibly sure. God’s revelation is true, whatever man’s dreams may be. On the basis of revelation there is foothold. A personal knowledge of Christ revealed by the Spirit is also a sure matter. I get to Jesus, I speak to Him, and meditate upon Him, and He rises before me greater than ever, till in His presence all the learning of men condenses into folly. He is “God only wise.” Ah, then I live when He is all in all! My heart is glad and my glory rejoiceth when I forget all else save Christ Jesus my Lord. Therefore, brethren, I say that you shall find a great reward in full often coming near to your Lord, and considering again and again how great He is. ~ C.H. Spurgeon
