31 Therefore when we could bear it no longer, we were willing to be left behind at Athens alone, 2 and we sent Timothy, our brother and God's coworker[1] in the gospel of Christ, to establish and exhort you in your faith, 3 that no one be moved by these afflictions. For you yourselves know that we are destined for this. 4 For when we were with you, we kept telling you beforehand that we were to suffer affliction, just as it has come to pass, and just as you know. 5 For this reason, when I could bear it no longer, I sent to learn about your faith, for fear that somehow the tempter had tempted you and our labor would be in vain.

6 But now that Timothy has come to us from you, and has brought us the good news of your faith and love and reported that you always remember us kindly and long to see us, as we long to see you-- 7 for this reason, brothers,[2] in all our distress and affliction we have been comforted about you through your faith. 8 For now we live, if you are standing fast in the Lord. 9 For what thanksgiving can we return to God for you, for all the joy that we feel for your sake before our God, 10 as we pray most earnestly night and day that we may see you face to face and supply what is lacking in your faith?

Commentary on 1 Thessalonians 3:1-5

(Read 1 Thessalonians 3:1-5)

The more we find pleasure in the ways of God, the more we shall desire to persevere therein. The apostle's design was to establish and comfort the Thessalonians as to the object of their faith, that Jesus Christ was the Saviour of the world; and as to the recompence of faith, which was more than enough to make up all their losses, and to reward all their labours. But he feared his labours would be in vain. If the devil cannot hinder ministers from labouring in the word and doctrine, he will, if possible, hinder the success of their labours. No one would willingly labour in vain. It is the will and purpose of God, that we enter into his kingdom through many afflictions. And the apostles, far from flattering people with the expectation of worldly prosperity in religion, told them plainly they must count upon trouble in the flesh. Herein they followed the example of their great Master, the Author of our faith. Christians were in danger, and they should be forewarned; they will thus be kept from being improved by any devices of the tempter.

Commentary on 1 Thessalonians 3:6-10

(Read 1 Thessalonians 3:6-10)

Thankfulness to God is very imperfect in the present state; but one great end of the ministry of the word is to help faith forward. That which was the instrument to obtain faith, is also the means of increasing and confirming it, namely, the ordinances of God; and as faith cometh by hearing, so it is confirmed by hearing also.
