2 Timothy 2:25

In meekness instructing those that oppose themselves
To the truth; resist it and deny it; or contradict some other tenets and principles of theirs, or the Scriptures, which they themselves allowed to be the word of God, and the rule of faith and practice, and so are self-convinced and self-condemned. These are to be instructed, being ignorant, and in a tender and gentle manner, though very perverse and obstinate.

If God peradventure will give them repentance to the acknowledging
of the truth:
repentance here designs a repentance of errors in principle, a change of mind upon conviction, and such as issues in a free and ingenuous confession, and acknowledgment of the truth before opposed; and such a repentance is the gift of God: it is he that opens the eyes of the understanding, and works conviction in the mind, and leads into all truth, as it is in Jesus; and induces men to repent of their errors, confess their mistakes, and own the truth; even as repentance of evil practices is not owing to the power of men, nor to the bare influence of means, but to the efficacious grace of God, it being a grant from him. And though this is not certain, that God will give repentance to such contradictors and blasphemers of his Gospel; yet as it is his will, that all his chosen ones should come to repentance, and that some of all sorts should be saved, and come to the knowledge of the truth; and seeing these things have been brought about under and by the ministry of the word, it is an encouragement to the ministers of the Gospel to continue their instructions in the manner here directed.
