5:16-22 We are to rejoice in creature-comforts, as if we rejoiced not, and must not expect to live many years, and rejoice in them all; but if we do rejoice in God, we may do that evermore. A truly religious life is a life of constant joy. And we should rejoice more, if we prayed more. Prayer will help forward all lawful business, and every good work. If we pray without ceasing, we shall not want matter for thanksgiving in every thing. We shall see cause to give thanks for sparing and preventing, for common and uncommon, past and present, temporal and spiritual mercies. Not only for prosperous and pleasing, but also for afflicting providences, for chastisements and corrections; for God designs all for our good, though we at present see not how they tend to it. Quench not the Spirit. Christians are said to be baptized with the Holy Ghost and with fire. He worketh as fire, by enlightening, enlivening, and purifying the souls of men. As fire is put out by taking away fuel, and as it is quenched by pouring water, or putting a great deal of earth upon it; so we must be careful not to quench the Holy Spirit, by indulging carnal lusts and affections, minding only earthly things. Believers often hinder their growth in grace, by not giving themselves up to the spiritual affections raised in their hearts by the Holy Spirit. By prophesyings, here understand the preaching of the word, the interpreting and applying the Scriptures. We must not despise preaching, though it is plain, and we are told no more than what we knew before. We must search the Scriptures. And proving all things must be to hold fast that which is good. We should abstain from sin, and whatever looks like sin, leads to it, and borders upon it. He who is not shy of the appearances of sin, who shuns not the occasions of it, and who avoids not the temptations and approaches to it, will not long keep from doing sin.
22. Tittmann supports English Version, "from every evil appearance" or "semblance." The context, however, does not refer to evil appearances IN OURSELVES which we ought to abstain from, but to holding ourselves aloof from every evil appearance IN OTHERS; as for instance, in the pretenders to spirit-inspired prophesyings. In many cases the Christian should not abstain from what has the semblance ("appearance") of evil, though really good. Jesus healed on the sabbath, and ate with publicans and sinners, acts which wore the appearance of evil, but which were not to be abstained from on that account, being really good. I agree with Tittmann rather than with Bengel, whom Alford follows. The context favors this sense: However specious be the form or outward appearance of such would-be prophets and their prophesyings, hold yourselves aloof from every such form when it is evil, literally, "Hold yourselves aloof from every evil appearance" or "form."
