(24) Faithful is he.--A reason for hoping confidently that they will be blamelessly preserved. God would forfeit His character for keeping His promise, if He "called," and did not enable men to obey the call. Of course He can only "do it" in case they continue willing to have it done. On the present tense, see Note on 1Thessalonians 2:12.

Verse 24. - Faithful is he that calleth you. Paul knows that he does not beseech God in vain. He who calls you to the Christian faith is faithful to fulfill his promises. God's calling is the commencement of a series which terminates in glorification (Romans 8:30). A similar appeal to the faithfulness of God is elsewhere made by the apostle (1 Corinthians 1:9; 2 Thessalonians 3:3). Who also will do it; namely, will preserve you blameless unto the coming of the Lord Jesus Christ.

5:23-28 The apostle prays that they might be sanctified more perfectly, for the best are sanctified but in part while in this world; therefore we should pray for, and press toward, complete holiness. And as we must fall, if God did not carry on his good work in the soul, we should pray to God to perfect his work, till we are presented faultless before the throne of his glory. We should pray for one another; and brethren should thus express brotherly love. This epistle was to be read to all the brethren. Not only are the common people allowed to read the Scriptures, but it is their duty, and what they should be persuaded to do. The word of God should not be kept in an unknown tongue, but transplanted, that as all men are concerned to know the Scriptures, so they all may be able to read them. The Scriptures should be read in all public congregations, for the benefit of the unlearned especially. We need no more to make us happy, than to know the grace of our Lord Jesus Christ. He is an ever-flowing and an over-flowing fountain of grace to supply all our wants.Faithful is he that calleth you,.... Into the fellowship of his Son, and to his kingdom and glory, and who continues to do so, not only externally by his word, but internally by his Spirit and grace.

Who also will do it. Two things the apostle mentions as the ground of confidence that the above petition, would be heard and answered; that is, that God would wholly sanctify them, and preserve the whole of them blameless to the coming of Christ; and they are the faithfulness of God, and the effectual calling of his saints. God is faithful to his word, his covenant and promises; he has promised to sanctify and cleanse his people from all their sins, and to preserve them safe to his kingdom and glory; agreeably the Arabic version renders this last clause, "and will execute his promise": and the effectual calling is a sure pledge of glorification; whom God calls he justifies and glorifies; as sure as he gives grace, he will give glory; and whom he calls to his eternal glory, he will make perfect, stablish, strengthen, and settle. The Complutensian edition reads, "who also will make your hope firm"; that is, with respect to the above things.
