…but unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.”- 1Cr 1:24

The call which saves is like that of Jesus, when He said “Mary,” and she said unto Him “Rabonni.” Do you know anything about that special call, my beloved? Did Jesus ever call you by name? Canst thou recollect the hour when He whispered thy name in thine ear, when He said, “Come to Me”? If so, you will grant the truth of what I am going to say next about it-that it is an effectual call; there is no resisting it. When God calls with His special call, there is no standing out. Ah! I know I laughed at religion; I despised it, I abhorred it; but that call! Oh, I would not come. But God said, “Thou shalt come. All that the Father giveth to Me shall come.” “Lord, I will not.” “But thou shalt,” said God. And I have gone up to God’s house sometimes almost with a resolution that I would not listen, but listen I must. Oh, how the word came into my soul! Was there a power of resistance? No; I was thrown down; each bone seemed to be broken; I was saved by effectual grace. I appeal to your experience, my friends. When God took you in hand, could you withstand Him? You stood against your minister times enough. Sickness did not break you down; disease did not bring you to God’s feet; eloquence did not convince you; but when God puts His hand to the work, ah! then what a change. Like Saul, with his horses going to Damascus, that voice from heaven said, “I am Jesus whom thou persecutest.” “Saul, Saul, why persecutest thou Me?” There was no going further then. That was an effectual call. ~ C.H. Spurgeon
