From Spurgeon Gold

Judas was a Preacher Judas was a preacher; nay, he was a foremost preacher, “he obtained part of this ministry,” said the Apostle Peter. He was not simply one of the seventy; he had been selected by the Lord himself as one of the twelve, an honorable member of the college of the apostles. Doubtless he had preached the gospel so that many had been gladdened by his voice, and miraculous powers had been vouchsafed to him, so that at his word the sick had been healed, deaf ears had been opened; and the blind had been made to see; nay, there is no doubt that he who could not keep the devil out of himself, had cast devils out of others. Yet how are you fallen from Heaven, O Lucifer, son of the morning! He that was as a prophet in the midst of the people, and spake with the tongue of the learned, whose word and wonders proved that he had been with Jesus and had learned of him — he betrays his Master. Understand, my brethren, that no gifts can ensure grace, and that no position of honor or usefulness in the Church will necessarily prove our being true to our Lord and Master. Doubtless there are bishops in Hell, and crowds of those who once occupied the pulpit are now condemned for ever to bewail their hypocrisy. You that are Church-officers, do not conclude that because you enjoy the confidence of the Church, that therefore of an absolute certainty the grace of God is in you. Perhaps it is the most dangerous of all positions for a man to become well known and much respected by the religious world, and yet to be rotten at the core. To be where others can observe our faults is a healthy thing though painful; but to live with beloved friends who would not believe it possible for us to do wrong, and who if they saw us err would make excuses for us — this is to be where it is next to impossible for us ever to be aroused if our hearts be not right with God. To have a fair reputation and a false heart is to stand upon the brink of Hell.
