The people therefore that was with Him when He called Lazarus out of his grave, and raised him from the dead, bare record. – John 12:17

It was a time of testimony: for those who had been present, and had seen Lazarus raised from the dead, bore witness. One stepped forward and said, “With these eyes I saw Lazarus come forth from the tomb of rock.” “As for me”, said another, “I saw him buried, I helped to carry him to the grave; but I saw him come back to the house alive.” “Yes”, said a third, “I rolled away the stone, and as I stood watching for the result, I saw the dead man come forth alive, and I helped to loose his grave-clothes.” All these bore witness to what they had seen. You cannot tell what a joyful effect it produces, and what enthusiasm is stirred, when one after another bears personal witness. Lord, open men’s mouths! Lord, make the quiet ones to tell forth Thy praise! Your silent tongues deprive us of our joy. Your cowardly reticence robs Christ of His glory and the church of its increase. If God has done anything for you, or you have seen Him do anything for others, bear testimony to it. It is the Lord’s due, and your duty, that you should speak to the glory of Christ Jesus. When great wonders have been done, and those who saw them are willing to bear their testimony “hereunto, then we may look for red-letter days, wherein gladness and praise shall be in the ascendant.

When we are all ready, each man, each woman, ready to take our share in the harvesting, then will the sheaves be garnered. It is cheering when the congregation shares the excitement with the church and its ministers, and the prospect of a divine blessing is before the mind of all who seek better things. Surely, the time to favor Zion, yea, the set time has come, when her King is longed for, and every heart beats high with love of Him. ~ C.H. Spurgeon
