3:11-13 Prayer is religious worship, and all religious worship is due unto God only. Prayer is to be offered to God as our Father. Prayer is not only to be offered in the name of Christ, but offered up to Christ himself, as our Lord and our Saviour. Let us acknowledge God in all our ways, and he will direct our paths. Mutual love is required of all Christians. And love is of God, and is fulfilling the gospel as well as the law. We need the Spirit's influences in order to our growth in grace; and the way to obtain them, is prayer. Holiness is required of all who would go to heaven; and we must act so that we do not contradict the profession we make of holiness. The Lord Jesus will certainly come in his glory; his saints will come with him. Then the excellence as well as the necessity of holiness will appear; and without this no hearts shall be established at that day, nor shall any avoid condemnation.

before God, even our Father—rather, "before Him who is at once God and our Father." Before not merely men, but Him who will not be deceived by the mere show of holiness, that is, may your holiness be such as will stand His searching scrutiny.

with all his saints—including both the holy angels and the holy elect of men (1Th 4:14; Da 7:10; Zec 14:5; Mt 25:31; 2Th 1:7). The saints are "His" (Ac 9:13). We must have "holiness" if we are to be numbered with His holy ones or "saints." On "unblameable," compare Re 14:5. This verse (compare 1Th 3:12) shows that "love" is the spring of true "holiness" (Mt 5:44-48; Ro 13:10; Col 3:14). God is He who really "stablishes"; Timothy and other ministers are but instruments (1Th 3:2) in "stablishing."
