Hebrews 5:14 But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.

I have said that we must learn always to discriminate, and at this particular time this point needs insisting on. Many run after novelties, charmed with every new thing; learn to judge between truth and its counterfeits, and you will not be led astray. Others adhere like limpets to old teachings, and yet these may only be ancient errors: prove all things, and hold fast that which is good. The use of the sieve, and the winnowing fan, is much to be commended. Dear brethren, a man who has asked of the Lord to give him clear eyes by which he shall see the truth and discern its bearings, and who, by reason of the constant exercise of his faculties, has obtained an accurate judgment, is one fit to be a leader of the Lordís host, but all are not such. It is painful to observe how many embrace anything if it be but earnestly brought before them. They swallow the medicine of every spiritual quack who has enough of brazen assurance to appear to be sincere. Be not children in understanding, test that which claims your faith. Ask the Holy Spirit to give you the faculty of discerning, so shall you conduct your flocks far from poisonous meadows, and lead them into safe pasturage.
