For you are our glory and joy. The meaning is, that the source of happiness to a minister of the gospel in the day of judgment will be the conversion and salvation of souls. The object of the apostle in dwelling on this, in a manner so tender and affectionate, is to show them that his leaving them, and his long absence from them, were not caused by any want of affection for them.

REMARKS on First Thessalonians Chapter 2

Ministers of the gospel should be entirely sincere, and without guile. They should attempt to carry no measure—not even the conversion of sinners—by trick or management ([Reference 1 Thessalonians 2:3-5]).
They should not make it a point to please men ([Reference 2 Thessalonians 2:4]). If they do please men, or if their ministry is acceptable to men, they should not regard it, indeed, as proof that they are unfaithful, for they should have a good report of them that are without; nor should they make it a point to displease men, or consider it a proof that because men are offended, therefore they are faithful; but it should not be their leading aim or purpose to gratify men. They should preach the truth; and if they do this, God will take care of their reputation, and give them just as much as they ought to have. The same principle should operate with all Christians. They should do right, and leave their reputation with God.
Ministers of the gospel should be gentle, tender, and affectionate. They should be kind in feeling, and courteous in manner—like a father or mother ([Reference 2 Thessalonians 2:7], 11). Nothing is ever gained by a sour, harsh, crabbed, dissatisfied manner. Sinners are never scolded either into duty or into heaven.
"Flies are not caught with vinegar." No man is a better or more faithful preacher because he is rough in manner, coarse or harsh in his expressions, or sour in his intercourse with mankind. Not thus was the Master, or Paul. There is no crime in being polite and courteous; none in observing the rules of good-breeding, and paying respect to the sensibilities of others; and there is no piety in outraging all the laws which society has found necessary to adopt to promote happy intercourse. What is wrong we should indeed oppose, but it should be in the kindest manner towards the persons of those who do wrong; what is true and right we should maintain and defend—and we shall always do it more effectually if we do it kindly.
Ministers should be willing to labour in any proper calling, if it is necessary for their own support, or to do good ([Reference 1 Thessalonians 2:9]). It is, indeed, the duty of a people to support the gospel, but there may be situations where they are not able to do it; and a minister should be able to earn something in some other way, and should be willing to do it.
Paul made tents; and if he were willing to do that, a minister should not feel himself degraded if he be obliged to make shoes, or to hoe corn, or to plough, or to keep cattle. He had better not do it, if he can avoid it well, for he needs his time for his more important work; but he should feel it no dishonour if he be obliged to do it, and should feel that it is a privilege to preach the gospel even if he be obliged to support himself by making either tents or shoes. It is no dishonour for a minister to work hard; and it is not well for a man to enter the ministry wholly unacquainted with every other way of procuring an honest living.
Every minister should be able to appeal to the people among whom he has laboured in proof that he is an honest man, and lives consistently with his profession ([Reference 1 Thessalonians 2:1], 9-11).
The same remark applies to all other Christians. They should so live that they may at once refer to their neighbours in proof of the uprightness of their lives, and their consistent walk. But to be enabled to do this, a man should live as he ought; for the world generally forms a very correct estimate of character.
The joy of a minister in the day of judgment will be measured by the amount of good which he has done, and the number of souls which he has been the means of converting and saving ([Reference 1 Thessalonians 2:19]). It will not be the honour which he has received from men; the titles which they have conferred on him; the commendation which he has received for eloquence or talent, or the learning which he has acquired; but it will be found in the number of those who have been converted from the error of their ways, and in the evidence of the good which he did on the earth.
And will not the same thing be substantially true of all others who bear the Christian name? Will it then be a source of joy to them that they were richer than their neighbours; or that they were advanced to higher honours; or that they had a more splendid mansion; or were able to fare more "sumptuously?" The good that we do will be remembered certainly with pleasure in the day of judgment: of how many other things which now interest us so much, can the same thing be said?
Paul expected evidently to recognise the Thessalonian Christians at the day of judgment, for he said that they would be then his joy and crown of rejoicing, ([Reference 1 Thessalonians 2:19]). But this could not be, unless he should be able to know those who had been converted by his instrumentality.
If he expected then to recognise them, and to rejoice with them, then we also may hope to know our pious friends in that happy world. Nothing in the Bible forbids this hope; and we can hardly believe that God has created the strong ties which bind us to each other, to endure for the present life only.
If Paul hoped to meet those who had been converted by his instrumentality, and to rejoice with them there, then the parent may hope to meet the child over whose loss he mourned; the husband and wife will meet again; the pious children of a family will be re-assembled; and the pastor and his flock will be permitted to rejoice together before the Lord.
This hope, which nothing in the Bible forbids us to entertain, should do much to alleviate the sorrow of the parting pang, and may be an important and powerful inducement to draw our own thoughts to a brighter and a better world. Of many of the living it is true that the best and dearest friends which they have are already in heaven—and how should their own hearts pant that they may meet them there!
