The Apostle knew of the faith and goodness of the Ephesians' character, having lived with them so long. When he says, "having heard," he makes known that since he had been separated from them, they had not only remained unchanged, but had preserved what had been sown in them and were advancing in it. They were building their salvation on it as on a firm foundation.
Blessed Theodoret writes: "From this, that he said 'having heard,' some concluded that the Apostle wrote this epistle without yet having seen the Ephesians. But one must know that he also wrote an epistle to the Corinthians after hearing something unpleasant about them. For he says: 'It has been reported to me concerning you, my brethren, by Chloe's people, that there are divisions among you' (1 Cor 1:11). Therefore, as there he writes with sorrow after learning something unpleasant, so here, having heard something joyful about the Ephesians, he composes praise for them."
Hearing of the good condition of the Ephesians and foreseeing what they will be deemed worthy of for this, the Apostle rejoices with them and counts their good as his own. Therefore he thanks God. This is his apostolic spirit. His apostolic heart, caring fatherly for those converted, moved him to this.
"There was nothing comparable to the Apostle's tender compassion," says Saint Chrysostom, "nothing like that participation and tender love with which blessed Paul was filled. In all his prayers he remembered whole cities and peoples. 'I thank God for you, making mention of you in my prayers.' Thus he usually wrote to all. Imagine, then, how many he had in his thought. Even to remember them was difficult, so many were those for whom he prayed, thanking God for all, as though he himself had received the greatest benefits which they had received."
So too everyone must thank God for others when seeing their progress in faith and love. One must thank God for their spiritual perfection, and not envy them, seeing in their perfection the glory of the Church. But over the scarcity of such people one must grieve and be contrite. One must pray to God that they may not decrease in the Church, but multiply, so that those strong in faith, knowledgeable in the faith, and active according to faith may always predominate in her.
"Making mention of you in my prayers." Every time I pray, I remember you. Every time I remember you, I thank God for you, because He has given you to believe and to live according to faith, so that both here and in the future life you may be partakers of all the blessings in the Lord.
But for one thing the Apostle gives thanks, and for another he asks. What exactly he asks is set forth in the following verses: that God would lead them more deeply into the contemplation of the mysteries of salvation in the Lord.
Yet thanksgiving alone is already a petition. The one who gives thanks values the gift. The one who values the gift will use it as he should. The one who knows how to use gifts disposes the Giver to pour out still more mercies upon him.
One can limit the whole prayer to thanksgiving, in the faith that both what is given and what is not given are all according to God's good pleasure toward us. He alone knows that it is good to give one thing and better not to give another.
Such a man stands reverently before the bountiful Giver, always in thankful feelings, because there is no moment when we are not enjoying His mercies. He does not dare to ask for more, not intruding into the mysteries of God's good pleasure toward us. So it is with regard to oneself.
To express good wishes for others and to pray to the Lord for them is not out of place even with such a disposition. This is the fruit of love and stirs up God's love. For this reason it is quickly heard and fruitful.
Yet let this also be known: the one who asks for others does not become the cause of the gift, but only a fellow-helper of it. The gift is still wholly from God's good pleasure and is conditioned by the proper disposition of those who receive it. When there is no receptacle in them, all heaven will not obtain anything for them by prayer. There is nothing into which the requested gift can be placed. Even apart from this, God desires every good thing for all. If not all have it, this is no longer from Him.
