The passage
      v1. Just as we have formal ways of introducing letters, so in the first Century there was a common letter form. Paul's letter to the Thessalonians follows this accepted form, demonstrating that it is in fact a letter and not just a theological treatise. Paul begins by telling us who it's from and who it's too, and then he greets his readers. Usually the Greeks just wrote the word "greeting", although Paul writes "grace". The word "grace" is derived from the Greek word "greeting", but is used here to sum up the gospel. "Grace" depicts God's total acceptance of a believer apart from their worthiness, or unworthiness, and this as a gift for the asking. The word "peace" is the common Jewish greeting. It means not so much a freedom from trouble, but more a wish for prosperity, wholeness.
      v2-3. Paul affirms that the Thessalonian church is central in his prayers, although he is not saying that each time he prays they are mentioned. In his prayers he brings before the Lord three qualities in the church for which he gives thanks:
        i] "Your work of faith". Paul gives thanks for their "active/effective faith", for the business side of their faith, the doing of it, the practice of faith.
        ii] "Your labor of love." Paul thanks God for their love, a love that labours to the point of weariness. The word he chooses is not often used in Greek writings of the day. The usual word for love referred to the human emotion or feeling of love - regarding someone or something very highly and with desire. The word for love used in the New Testament takes on its own meaning. It is something that can only be understood by examining the character of God. It is a costly compassion toward another prompted by no worthiness, or future worthiness, in the one so loved. Such love can only be imaged in the death of Jesus on our behalf.
        iii] "Your patient hope." Paul thanks God for their "patient hope" - "a spirit which can bear all things, not simply with resignation, but with blazing hope", Barclay. They have a sure belief in God's ultimate purpose.
      "In the Lord Jesus Christ." This phrase either refers to "hope", or to all three qualities. Probably all three is best. Our whole life, and in particular "faith, hope and love", is lived out in our relationship with Jesus. Such is only possible through him and in relationship with him.

Faith, Hope and Love
      Life prepares us for eternity. As we walk with Jesus day-by-day we take on qualities imaged in his character. Although these qualities serve us here on earth, they are especially useful for our rule with Christ in eternity. The scriptures identify three prime qualities found in Jesus' person, and they are qualities that we should nurture in our own lives. They are faith, hope and love.
      Paul, writing to the Thessalonian Christians, observes these qualities in their church fellowship, and he gives thanks to God for them. They are qualities that should be found in every church, in every Christian life, and so they are qualities we should aspire to possess.
        i] "Active faith". Possessing a faith that is active and maturing in its effectiveness, is going to be essential for our rule with Christ in eternity. Building the muscles of faith requires going out on a limb for the Lord, it involves trusting him when all about us denies the wisdom of that trust. The Thessalonians, since the departure of Paul, had to stand firm in the face of disbelief and opposition. The Thessalonians were now on their own, yet they did not waver in their reliance on the Lord. "Timothy has just now come to us from you and has brought good news about your faith and love." Growing in our reliance upon the one who travels with us through life, learning to trust in the living Lord, learning to trust as he trusted, this must be our goal.
        ii] "Love that labours". Love is the greatest of the eternal qualities. In fact, it sums up the very character of God. "God is Love". Love is a quality that should consume us and it was Paul's prayer for the Thessalonians. "May the Lord make your love increase and overflow for each other and for everyone else." To begin to possess a love that labours for others, that seeks the best for others, is to be touched by the grace of God. A natural love cares for those we regard highly and want to possess for our own pleasure, yet self-giving love, the love that Christ exhibits, now there is a miracle. Let us look to Jesus that this love may grow in us as a gift of God's grace.
        iii] "Patient Hope". Developing a burning confidence in the ultimate intentions of God, enables us to stand steadfast in the present. It is as we develop a sure and steady hope in the coming kingdom, that we then begin to handle the present momentary troubles we face. We must pray that our confidence in the future intentions of God will grow with every passing day.

v2
      pantote adv. "always" - Possibly meaning that every time Paul prays he doesn't fail to mention the Thessalonians, or that when he prays for them he doesn't fail to give thanks for them, "we are always thankful as we pray for you all", Phillips.
