1 Thessalonians 3:13

to the end he may establish your hearts unblamable in holiness before God, even our father, at the coming of our Lord Jesus Christ with all His saints.

Paul here rises to an enthusiasm bordering on ecstasy. The high satisfaction and peculiar joy which he felt are strongly shown in the language which he uses: What sufficient thanks can I render to God, in return, concerning you for all the joy with which we rejoice on your account before our God, night and day praying most fervently that we may see your face, and might perfect the deficiencies of your faith? The apostle has received definite information of the stability of the Thessalonians in faith. This wonderful condition he attributes entirely to God, whose power has been manifested through the Gospel. He is anxious to make some return of appropriate thanksgiving to the Lord of grace; he is casting about for ways and means which would adequately express the gratitude which is overflowing from his heart. His reason for thanksgiving he has in the joy which is now striving for utterance, in his exultant rejoicing on their account. Without ceasing, night and day, his fervent supplications are rising to the Throne of Grace that God would grant him the boon of seeing his pupils at Thessalonica face to face. For that would give him an opportunity of perfecting any deficiencies which their faith still had, it would give him the chance to rectify certain matters of belief and practice. The Thessalonians were still in need of instruction, of exhortation, of intercession; for no Christians attain to complete perfection in this life. The fundamental outlines of the truth were in their possession, but it was necessary to fill out these outlines, to supply the details, to make them perfectly fitted to every good word and work.

The prayer of the apostle now rises to still greater heights of fervor: But God Himself and our Father and our Lord Jesus Christ direct our way to you; you, however, may the Lord cause to increase and to excel in love toward one another and toward all, just as we stand toward you, in order that He may establish your hearts irreproachable in holiness before God and our Father at the coming (the royal visit) of our Lord Jesus Christ with all His saints. Amen. The first petition of the apostle concerns himself, namely, that God would so arrange it, would so guide and direct matters, that it would be possible for him to visit Thessalonica as soon as possible, Note that his prayer is directed to both God the Father and to the Lord Jesus Christ, these two persons of the Godhead being equal in deity. Mark also that every prayer is heard by God through Jesus Christ, by whom we have access to the Father, in whom the Father gives all His gifts to His children on earth. Should there be any delay in his coming, however, or, no matter what would happen, he has another petition, namely, that the Lord, the Giver of all good gifts, would cause the Thessalonian Christians to become filled with, to increase in, love, and thus to excel, to superabound in love toward one another, in the midst of their own congregation and toward all men. In this respect Paul was their example and model, in the love which he bore them. The result of this work of the Lord would be that the hearts of all the believers in the congregation would be established as being without reproach in holiness. This includes the whole life in and from the Spirit. The purity and the soundness of a Christian's holiness is based upon the disinterestedness of his love toward his fellow-Christians and toward all men. Thus would the Thessalonian Christians be prepared to stand before God the Father on the great day when our Lord Jesus Christ will pay His promised royal visit to the earth in visible form, accompanied by all His holy angels and the saints from heaven, Hebrews 12:22; Luke 20:26. Mark: The apostle never fails to call attention to the end and aim of the Christian life, the perfection of heaven, the reward of grace to those that remain steadfast in faith and love, in holiness of life, to the end.

Summary

The apostle gives further proof of his love for the Thessalonians in that he had sent Timothy to strengthen them, whose excellent report concerning their firmness had comforted him greatly; he includes a prayer for their further establishment in faith and love unto the end.
