And the Lord make you to increase
That is, the Lord the Spirit; so that the object of prayer, addressed by the apostle, is Father, Son, and Spirit, as in ( Revelation 1:4 Revelation 1:5 ) . The Alexandrian copy reads "God". The Spirit is God, equally with the Father and the Son, and so a fit object of prayer with them, which otherwise he would not be. The request is, that he would cause these saints to increase in number, as the first churches greatly did: and in the gifts of the Spirit, which he divides to men severally as he will; and in his graces, as in faith, in hope, in holiness, in humility, in knowledge, in spiritual joy and strength, an increase in all which is from him:
and abound in love one towards another;
for though they were taught of God to love one another, and did do so, and the apostle had had good tidings of their love; yet it was not perfect, there was room for a further exercise of it, by serving each other by it, in things spiritual and temporal; and he had his request, for it did abound in everyone of them towards each other, ( 2 Thessalonians 1:3 )
and towards all men;
the men of the world, who were without, were not members of the church, nor professors of the Christian religion, but enemies to that, and to Christ, and to them; and yet they were to love them as men, and pray for them, and do them all the good that lay in their power:
even as we do towards you;
for the love of the apostle, and those with him, abounded more and more towards these saints, and was so far from being weakened, that it was increased by their absence from them; and they were more abundantly desirous of seeing them, and were even quite impatient until they sent to them, and heard of them.
