2 Corinthians 3:4

“And such trust have we, etc..] This refers to what he had said in the latter end of the foregoing chapter, and the beginning of this; as that they made manifest the savoury knowledge of God and Christ everywhere, and were the sweet savour of Christ to many souls; were sufficient in some measure, through the grace of Christ, to preach the Gospel sincerely and faithfully, and were attended with success, had many seals of their ministry, and particularly the Corinthians were so many living epistles of commendations of the power and efficacy of their ministry; such confidence and firm persuasion of the truth of grace on your souls, and of our being the happy instruments of it, we have through…”

“And--Greek, "But." "Such confidence, however (namely, of our 'sufficiency,' Co2 3:5-6; Co2 2:16 --to which he reverts after the parenthesis--as ministers of the New Testament, 'not hinting,' Co2 4:1), we have through Christ (not through ourselves, compare Co2 3:18) toward God" (that is, in our relation to God and His work, the ministry committed by Him to us, for which we must render an account to Him). Confidence toward God is solid and real, as looking to Him for the strength needed now, and also for the reward of grace to be given hereafter. Compare Act 24:15, "hope toward God." Human confidence is unreal in that it looks to man for its help and its reward.”

“And such trust have we - Such confidence have we that we are appointed by God, and that he accepts our work. Such evidence have we in the success of our labors; such irrefragable proof that God blesses us; that we have trust, or confidence, that we are sent by God, and are owned by him in our ministry. His confidence did not rest on letters of introduction from people, but in the evidence of the divine presence, and the divine acceptance of his work. Through Christ - By the agency of Christ. Paul had no success which he did not trace to him; he had no joy of which he was not the source; he had no confidence, or trust in God of which Christ was not the author; he had no hope of success in his…”

“Such trust have we in God - That is, we trust in God that this is so. 2 Corinthians 3:5”

“3:4-18 The contrast between Paul’s ministry and the others’ ministries leads Paul to contrast the old covenant of written laws (Exod 31:18) with the new covenant written on human hearts (Jer 31:33). 3:4-6 The old written covenant is the Mosaic law as interpreted by the Jewish rabbis. It ends in death for adherents who see it as a way of salvation. The law is good (Rom 7:12-14), but those who use it to gain merit fail. It leads either to transgression or to pride; either way, the law brings condemnation (2 Cor 3:9).”
