1 John 3:21 - Coke's Commentary on the Holy Bible

Beloved, if our heart condemn us not,— Though the expression is negative in the text, it must imply somewhat positive; namely, that conscience should upon examination acquit us. St. John is speaking here notof Jews, Heathens, Infidels, hypocrites, or vicious persons; but of himself, and other real Christians, who were experimentallyacquainted with the pure gospel, and might easily examine their hearts and lives thereby. If such, upon a careful examination, find a divine conformity to the rules of the gospel in their tempers and lives, they may be satisfied that their present state is good, and may with pleasure expect Christ's second coming. The philosophers have disputed much about tranquillity of mind; nevertheless there is nothing which can truly render our minds quiet, easy, and satisfied, but a just persuasion of the love of God toward us.
