(9) God is faithful.--The One who called them "unto the communion of His Son" is faithful, and therefore He will complete His work; no trials and sufferings need make them doubt that all will at last be well. The same confidence is expressed in Philippians 1:6, and 1Thessalonians 5:24.

Verse 9. - God is faithful. He will not leave his promises unfulfilled or his work unfinished (1 Corinthians 10:13; 2 Thessalonians 3:3; Hebrews 10:23; Romans 8:28-30). Through whom. By whom, as the moving cause and agent in your salvation. Ye were called. The calling was a pledge of the final blessing (Romans 8:30). Into the fellowship of his Son. Union (koinonia, communion) with Christ is the sole means of spiritual life (John 15:4; Galatians 2:20). Through the Son we also have fellowship with the Father (1 John 1:3). The perfect sincerity of the apostle is observable in this thanksgiving. He speaks of the Church in general in terms of gratitude and hopefulness, and dwells on its rich spiritual endowments; but he has not a word of praise for any moral advance such as that which he so lovingly recognized in the Thessalonians and Philippians.

1:1-9 All Christians are by baptism dedicated and devoted to Christ, and are under strict obligations to be holy. But in the true church of God are all who are sanctified in Christ Jesus, called to be saints, and who call upon him as God manifest in the flesh, for all the blessings of salvation; who acknowledge and obey him as their Lord, and as Lord of all; it includes no other persons. Christians are distinguished from the profane and atheists, that they dare not live without prayer; and they are distinguished from Jews and pagans, that they call on the name of Christ. Observe how often in these verses the apostle repeats the words, Our Lord Jesus Christ. He feared not to make too frequent or too honourable mention of him. To all who called upon Christ, the apostle gave his usual salutation, desiring, in their behalf, the pardoning mercy, sanctifying grace, and comforting peace of God, through Jesus Christ. Sinners can have no peace with God, nor any from him, but through Christ. He gives thanks for their conversion to the faith of Christ; that grace was given them by Jesus Christ. They had been enriched by him with all spiritual gifts. He speaks of utterance and knowledge. And where God has given these two gifts, he has given great power for usefulness. These were gifts of the Holy Ghost, by which God bore witness to the apostles. Those that wait for the coming of our Lord Jesus Christ, will be kept by him to the end; and those that are so, will be blameless in the day of Christ, made so by rich and free grace. How glorious are the hopes of such a privilege; to be kept by the power of Christ, from the power of our corruptions and Satan's temptations!God is faithful, by whom ye were called,.... These words contain arguments, assuring the saints of their confirmation in grace, and of their being preserved blameless to the day of Christ, taken from the faithfulness of God, who is always true to his promises: whatever he has said, he will do it; he will never suffer his faithfulness to fail; and since he has made so many promises concerning the establishment of his people, and their perseverance to grace, they may assure themselves of them; and also from his having called them by his grace, for whom he effectually calls by his grace, he glorifies; and particularly from his having called them

into the fellowship of his Son Jesus Christ our Lord; to partake of his grace, and to be heirs of glory with him; to enjoy communion with him in private and public exercises of religion, which is an evidence of being in him, and of union to him; for it is not merely into the fellowship of his saints or churches, but into the fellowship of his Son they are said to be called; and such are members of Christ, of his body, of his flesh, and of his bone; and shall never be lost and perish, but shall be confirmed to the end; be preserved in him blameless, and presented to him faultless, and have everlasting life.
