“The day following Jesus would go forth into Galilee, and findeth Philip.” – John 1:43

I was sitting down, one day, gratefully reflecting on what God had done for me. I knew that my sins were pardoned, I knew that I was accepted in Christ Jesus, and I knew that I was renewed in heart, and in one moment the revelation came to me: “All this is the work of God.” The instant I saw that truth, I said to myself, “Yes, that is the fact, and God be glorified for it! But why has this great work been wrought in me?” I knew that there was no merit in me before the Lord had dealt in mercy with my soul, so I said to myself, “This is the effect of sovereign distinguishing grace.” Then I understood in a moment how it is that God begins with us, and that it is God’s will and God’s eternal purpose, which, after all, lie deeper down than our will or our purpose; and God’s will and God’s eternal purpose must have the glory. What a revelation it was to me! I saw the doctrines of grace immediately; and I think that anybody who has been brought to find the Saviour, and who prayerfully studies the reasons for his salvation, can see the same truth that the Lord revealed to me. Because first of all, you began to be thoughtful, did you not? Who made you thoughtful? You would never have found the Savour if you had not become thoughtful instead of careless and indifferent. Who made you think of divine things? What influence was it which wrought upon you, and caused you to feel that you must think about eternity, and heaven, and hell? Then you had a sense of your need and of your sinfulness. There was a time when you had no such sense; then, who gave it to you? Where do you think that repentance, that sorrow for sin, that desire after Christ, came from? Did all that grow in your own fallen human nature? Ah, believe me, that dunghill never brought forth such fair flowers as these! No, it was Christ who sowed the good seed in your soul; it was He who made you feel your need of Him. Surely it was God the Holy Ghost going forth, in the name of Jesus Christ, and dealing with you in mercy. ~ C.H. Spurgeon
