Paul, and Silvanus, and Timotheus, unto the church of the Thessalonians which is in God the Father and in the Lord Jesus Christ: Grace be unto you, and peace, from God our Father, and the Lord Jesus Christ.

But brothers, after we were separated from you for a short time --- in person but not in spirit --- we became all the more eager [to come to you] and strongly desired to see you in person. [Note: The word "separated" here denotes the traumatic experience of a child being forcibly removed from its parents. It had been about six months since Paul left Thessalonica under adverse circumstances].

Wherefore we would have come unto you, even I Paul, once and again; but Satan hindered us.

For what is [the basis of] our hope, or joy, or crown of honor in the presence of the Lord Jesus when He comes back? [Note: By "crown" Paul alludes to the laurel wreath awarded to the victor in an athletic contest]. Will it not be you people?

So, when we could not stand it any longer [Note: Paul's concern for the spiritual well-being of the Thessalonian Christians became unbearable], we [i.e., I, See verse 5] thought it best to be left behind, alone, at Athens [Note: Paul was willing to labor alone at Athens, so he could send his fellow-workers to minister to others. See Acts 17],

for now we [really] live, if you [continue to] stand firm in [the service of] the Lord [i.e., Paul could enjoy life much more in knowing that the Thessalonians were living for the Lord faithfully].

For we say this to you by [the authority of] the word of the Lord [Note: Paul was either quoting what Jesus had previously said, or was giving a revelation he had received from the Lord. See I Cor. 14:37], that we [Christians] who are [still] alive, who are left [on earth] when the Lord returns, will certainly not precede those who have fallen asleep. [Note: The point Paul is making is that the living will not be "changed" (I Cor. 15:51-52) and taken to heaven before the dead are raised].
