Love doesn't mean never disapproving anybody's religious opinions

The love of the Bible does not consist in never disapproving anybody's religious opinions. Here is another most serious and growing delusion. There are many who pride themselves on never pronouncing others mistaken, whatever views they may hold. Your neighbor, for example, may be a Roman Catholic, or a Mormon. But the "love" of many says that you have no right to think him wrong! If he is sincere, it is "unloving" to think unfavorably of his spiritual condition! From such love may I ever be delivered! At this rate the Apostles were wrong in going out to preach to the Gentiles! At this rate there is no use in missions! At this rate we had better close our Bibles, and shut up our churches! Everybody is right, and nobody is wrong! Everybody is going to heaven, and nobody is going to hell!

Such love is a monstrous caricature. To say that all are equally right in their opinions, though their opinions flatly contradict one another—to say that all are equally on their way to heaven, though their doctrinal sentiments are as opposite as black and right—this is not Scriptural love. Love like this pours contempt on the Bible, and talks as if God had not given it as a written test of truth. Love like this confuses all our notions of heaven and would fill it with a discordant inharmonious rabble. True love does not think everybody is right in their doctrines. True love cries—"Do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world."—"If anyone comes to you and does not bring this teaching, do not take him into your house or welcome him" (2 John 1:10).
