It is to walk under sanctification by grace through His mysteries, and in the whole Christian order," says Bishop Theophan.
The Apostle explains exactly how one must walk in Christ by the words "rooted" and "built up." By them he suggests that Christians must grow as a tree grows, or as a newly constructed house rises.
"Rooted, that is, established, not being carried now to one path, now to another. What is rooted is never moved," says St. John Chrysostom.
"By the word built up, according to the explanation of Blessed Theodoret, the Apostle explains the acquisition of virtue."
"Have perfect faith, so that there may be no deficiency in it. Let it flow forth abundantly and abound exceedingly in you, so that you may hymn the Benefactor for all things."
"According to the teaching of the Apostle Paul, a man must be filled with a sense of gratitude in all his deeds (cf. Col 3:17; 4:2; Phil 4:6; 1 Thess 5:18).
This is still more so when he is conscious of progress in the work of religious and moral perfection" (N. Mukhin).
"Thanksgiving presupposes the tasting of the fruits of faith, and therefore a higher state of life in the realm of faith" (Bishop Theophan).
