"Hold fast that which is good." 1 Thessalonians 5:21

There are two things especially which every saint of God is called upon to hold fast: these are, first, the beginning of God's work upon his soul; and, secondly, his deliverance. Any manifestation too that you have had of the Lord Jesus Christ; any application of his atoning blood; any discovery of his glorious Person or shedding abroad of his love; hold that fast, for it is good.

And so I may say, hold fast any promise you have ever had applied; any answer to prayer you have ever received; any felt blessing that may have been wrought in your heart by a divine power. All this is good. It comes from a good God; it works in a good way; it leads to a good end; it will make a good deathbed, and will land you in a most blessed eternity. Therefore "hold fast that which is good."

Everything which is commended to your conscience as really good; every good man; every good minister; every child of God with whom you feel union or communion; every good precept, word, and work; in short, whatever is fully commended to your conscience as spiritual and divine, hold that fast, and you will find the benefit of it. Discard and reject everything bad, unbecoming, inconsistent, ungodly, erroneous, or heretical; discard them all—shew them no mercy. In heart but not in hand, hew them down, as Samuel hewed down Agag in Gilgal.
