1:21 {13} Now he which stablisheth us with you in Christ, and hath anointed us, [is] God;
(13) He attributes the praise of this constancy only to the grace of God, through the Holy Spirit. In addition he concludes that they cannot doubt of his faith and his fellows, without doing injury to the Spirit of God, seeing that they themselves know all this to be true.
1:21 Now he that stablisheth us with you in Christ. He gives us our stability so that our gospel is yea, sure and steadfast.
And hath anointed us. With the unction of the Holy Spirit (1Jo 2:20,27).
1:21 I say, to the glory of God - For it is God alone that is able to fulfil these promises. That establisheth us - Apostles and teachers. With you - All true believers. In the faith of Christ; and hath anointed us - With the oil of gladness, with joy in the Holy Ghost, thereby giving us strength both to do and suffer his will.
1:15-24 The apostle clears himself from the charge of levity and inconstancy, in not coming to Corinth. Good men should be careful to keep the reputation of sincerity and constancy; they should not resolve, but on careful thought; and they will not change unless for weighty reasons. Nothing can render God's promises more certain: his giving them through Christ, assures us they are his promises; as the wonders God wrought in the life, resurrection, and ascension of his Son, confirm faith. The Holy Spirit makes Christians firm in the faith of the gospel: the quickening of the Spirit is an earnest of everlasting life; and the comforts of the Spirit are an earnest of everlasting joy. The apostle desired to spare the blame he feared would be unavoidable, if he had gone to Corinth before he learned what effect his former letter produced. Our strength and ability are owing to faith; and our comfort and joy must flow from faith. The holy tempers and gracious fruits which attend faith, secure from delusion in so important a matter.
