When Paul was preaching the most important truths of the everlasting Gospel at Corinth, he was brought before the judgment-seat and accused for his doctrine. Poor Gallio would not concern himself about the matter: he looked on it all as a strife of words, and a contention about names. "I will be no judge," said he. He "cared for none of these things:" his heart was totally unacquainted with the faith of God's saints. Art thou a partaker of like precious faith with the apostles? And canst thou be a Gallio too? Know, if thou wilt not contend for the faith, that hell and earth are in arms to contend against it.
What is the faith here spoken of? It includes the doctrines of faith revealed in the word of God; the whole scheme of evangelical truth, inspired by the Spirit of truth: these are received by faith; are the rule, the warrant, the support, and the glory and joy of faith: such as the doctrine of the Trinity in unity: the everlasting covenant of grace: the result of God's everlasting love to his people: the incarnation of the Son of God to save us: our regeneration by the Spirit; and full and complete salvation by grace. It includes also the great object of faith: Christ received into the heart by faith, by whom we have peace with God, pardon of sin, justification, boldness to draw nigh to him, and sweet fellowship with him. Now these truths are delivered to, and received by saints.
Says Jude, "Beloved, it was needful that I should exhort you" –to what? To contend earnestly, heartily, with warmth of zeal, with a holy glow of affection, in good earnest. Disciple, improve this word of exhortation. Consider that the doctrines of the Gospel and your receiving them are of the greatest moment to your well-being as a christian. Some ignorantly call the doctrines of the Gospel mere opinions; just as if it was indifferent whether they are believed or not. Stand reproved, ye Laodicean spirits, who have not a word to say in defence of your most holy faith, but under a pretence of peace, are cool and indifferent about the truth. Truth is too great a price at which to purchase peace. But remember, faith works by love: contend only with the fire of love in your heart: eye Christ in all: aim at his glory by all: pray to have his mind accompany all: with love and pity to all, pray him to bless all who oppose you, if peradventure he may give them repentance to the acknowledging the truth. Titus 1:1.
