For Christ did not send me to baptize, but to preach the gospel, not with wisdom of words, lest the cross of Christ should be made of no effect. – 1 Corinthians 1:17

These disciples were to follow Christ that they might listen to Him, hear what He had to say, drink in His teaching, and then go and teach what He had taught them. Their Lord says, “What I tell you in darkness, speak ye in light: and what ye hear in the ear, that preach ye upon the housetops.” If they will be faithful reporters of Christ’s message, He will make them “fishers of men.” But you know the boastful method nowadays is this: “I am not going to preach this old, old gospel, this musty Puritan doctrine. I will sit down in my study, and burn the midnight oil, and invent a new theory; then I will come out with my brand-new thought, and blaze away with it.” Many are not following Christ, but following themselves, and of them the Lord may well say, “Thou shalt see whose word shall stand, Mine or theirs.” Others are wickedly prudent, and judge that certain truths which are evidently God’s word had better be kept back. You must not be rough, but must prophesy smooth things. To talk about the punishment of sin, to speak of eternal punishment, why, these are unfashionable doctrines. It may be that they are taught in the Word of God, but they do not suit the genius of the age. We must pare them down. Brothers in Christ, I will have no share in this. Will you? O my soul, come not thou into their secret!

Jesus says, “Follow Me, I will make you fishers of men;” but if you go in your own way, with your own net, you will make nothing of it, and the Lord promises you no help in it. The Lord’s directions make Himself our leader and example. It is, “Follow Me, follow Me. Preach My gospel. Preach what I preached. Teach what I taught, and keep to that.” With that blessed servility which becomes one whose ambition it is to be a copyist, and never to be an original, copy Christ even in jots and tittles. Do this, and He will make you fishers of men; but if you do not do this, you shall fish in vain.~ C.H. Spurgeon
