“Behold, he is a chosen vessel.”_ Acts 9:15

I often find people troubling themselves about the doctrine of election. Every now and then I get a letter from somebody or other taking me to task for preaching election. All the answer I can give is, “There it is in the Bible; go and ask my Master why He put it there. I cannot help it. I am only a serving man, and I tell you the message from above. If I were a footman, I should not alter my master’s message at the door. I happen to be an ambassador of heaven, and I dare not alter the message I have received. If it is wrong, send up to head-quarters. There it is, and I cannot alter it.” This much let me say in explanation. Some say, “How can I discover whether I am God’s elect? I am afraid I am not God’s elect.” Do you pray? If it can be said, “Behold, he prayeth,” it can also be said, Behold, he is a chosen vessel.” Have you faith? If so, you are elect. Those are the marks of election. If you have none of these, you have no grounds for concluding that you belong to the peculiar people of God. Have you a desire to believe? Have you a wish to love Christ? Have you the millionth part of a desire to come to Christ? And is it a practical desire? Does it lead you to offer earnest, tearful supplication? If so, never be afraid of non-election; for whoever prays with sincerity, is ordained of God before the foundation of the world, that he should be holy and without blame before Christ in love.~ C.H. Spurgeon
