41 Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, 2 speaking lies in hypocrisy, having their own conscience seared with a hot iron, 3 forbidding to marry, and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. 4 For every creature of God is good, and nothing is to be refused if it is received with thanksgiving; 5 for it is sanctified by the word of God and prayer.
6 If you instruct the brethren in these things, you will be a good minister of Jesus Christ, nourished in the words of faith and of the good doctrine which you have carefully followed. 7 But reject profane and old wives' fables, and exercise yourself toward godliness. 8 For bodily exercise profits a little, but godliness is profitable for all things, having promise of the life that now is and of that which is to come.
Matthew Henry's Commentary on 1 Timothy 4:1-8
Commentary on 1 Timothy 4:1-5
(Read 1 Timothy 4:1-5)
The Holy Spirit, both in the Old and the New Testament, spoke of a general turning from the faith of Christ, and the pure worship of God. This should come during the Christian dispensation, for those are called the latter days. False teachers forbid as evil what God has allowed, and command as a duty what he has left indifferent. We find exercise for watchfulness and self-denial, in attending to the requirements of God's law, without being tasked to imaginary duties, which reject what he has allowed. But nothing justifies an intemperate or improper use of things; and nothing will be good to us, unless we seek by prayer for the Lord's blessing upon it.
Commentary on 1 Timothy 4:6-10
(Read 1 Timothy 4:6-10)
Outward acts of self-denial profit little. What will it avail us to mortify the body, if we do not mortify sin? No diligence in mere outward things could be of much use. The gain of godliness lies much in the promise; and the promises to godly people relate partly to the life that now is, but especially to the life which is to come: though we lose for Christ, we shall not lose by him. If Christ be thus the Saviour of all men, then much more will he be the Rewarder of those who seek and serve him; he will provide well for those whom he has made new creatures.
