SEV Biblia, Chapter 1:18
Antes es Dios fiel que nuestra palabra para con vosotros no ha sido sí y no.
Clarke's Bible Commentary - 2 Corinthians 1:18
Verse 18. But as God is true] Setting the God of truth before my eyes, I could not act in this way: and as sure as he is true, so surely were my purposes sincere; and it was only my uncertainty about your state that induced me to postpone my visit. See ver. 23.
John Gill's Bible Commentary
Ver. 18. But as God is true , etc..] It seems that the false apostles had insinuated, that as the apostle had not kept his word in coming to them as he had promised, that he was not to be depended upon in his ministry; that he might as well contradict himself, and deceive others in the one, as well as in the other: wherefore he appeals to God in a very solemn manner, calls him to witness to the truth of his doctrine; for these words may be considered as the form of an oath; or he argues from, the truth and faithfulness of God, to the certainty and invariableness of the word preached, who is so true and faithful as that he will never suffer his word to be yea and nay: for when the apostle says, that our word towards you was not yea and nay , he does not mean his word of promise to come to Corinth; but the word of his preaching, the doctrine of the Gospel, which was not uncertain, changeable, sometimes one thing, and sometimes another, and contradictory to itself. And by this the apostle would intimate, that since he was faithful and upright, uniform, consistent, and all of a piece in preaching the Gospel to them; so they ought to believe, that he was sincere in his resolutions and promises to come and see them, though as yet he had been hindered, and had not been able to perform them.
Matthew Henry Commentary
Verses 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 of careful thought; and they will not change unless for weighty reasons Nothing can render God's promises more certain: his giving them throug 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 apostl desired to spare the blame he feared would be unavoidable, if he ha gone to Corinth before he learned what effect his former lette produced. Our strength and ability are owing to faith; and our comfor and joy must flow from faith. The holy tempers and gracious fruit which attend faith, secure from delusion in so important a matter __________________________________________________________________

Vincent's NT Word Studies
18. As God is true (pistov o Qeov). Not to be taken as a formula of swearing. He means that God will answer for him against the charge of fickleness by the power and blessing (benefit) which will attend his presence. Hence the meaning is: faithful is God (in this) that our speech, etc.
Robertson's NT Word Studies
1:18 {Is not yea and nay} (ouk estin nai kai ou). He is not a Yes and No man, saying Yes and meaning or acting No. Paul calls God to witness on this point.
