Spurgeon on the best approach to confront heresies

The following is excerpted from Spurgeon’s commentary on Ps 138.1:

“  “Before the gods will I sing praise unto thee.” Why should these idols rob Jehovah of his praises? The Psalmist will not for a moment suspend his songs because there are images before him, and their foolish worshippers might not approve of his music. I believe David referred to the false gods of the neighbouring nations, and the deities of the surviving Canaanites. He was not pleased that such gods were set up; but he intended to express at once his contempt of them, and his own absorption in the worship of the living Jehovah by continuing most earnestly to sing wherever he might be. It would be paying these dead idols too much respect to cease singing because they were perched aloft. In these days when new religions are daily excogitated, and new gods are set up, it is well to know how to act. Bitterness is forbidden, and controversy is apt to advertise the heresy; the very best method is to go on personally worshipping the Lord with unvarying zeal, singing with heart and voice his royal praises. Do they deny the Divinity of our Lord? Let us the more fervently adore him. Do they despise the atonement? Let us the more constantly proclaim it. Had half the time spent in councils and controversies been given to praising the Lord, the church would have been far sounder and stronger than she is at this day. The Hallelujah Legion will win the day. Praising and singing are our armour against the idolatries of heresy, our comfort under the depression caused by insolent attacks upon the truth, and our weapons for defending the gospel. Faith when displayed in cheerful courage, has about it a sacred contagion: others learn to believe in the Most High when they see his servant “Calm ’mid the bewildering cry, Confident of victory.” C. H. Spurgeon, [The Treasury of David: Psalms 120-150, vol. 6 (London; Edinburgh; New York: Marshall Brothers, n.d.), 243–244.]
