John Gill emphasizes the significance of experiencing the grace of the Lord Jesus Christ, as referenced in 1 Peter 2:3. He explains that true believers, having tasted the goodness of Christ, develop a spiritual appetite for His word and promises, contrasting them with the unregenerate who find no sweetness in spiritual matters. Gill highlights that this taste is not superficial but deeply rooted in a saving faith that leads to a transformative relationship with Christ. He encourages believers to continually seek nourishment from the Gospel, which reveals the glory and grace of Christ, fostering a desire for deeper understanding and growth in faith.

Ver. 3. If so be ye have tasted that the Lord is gracious. Reference is had to Ps 34:8, "O taste and see that the Lord is good"; and the Syriac version here adds, "if ye have seen": by the Lord is meant, the Lord Jesus Christ, as the following words show, who is gracious and amiable, and lovely in his person; who has a fulness of grace in him for his people; has displayed his grace towards them, in engaging for them as a surety, in assuming their nature, obeying, suffering, and dying in their stead; he is gracious in his word and promises, truths and ordinances, and in all his offices and relations; and regenerate persons have tasted that he is so: an unregenerate man has no spiritual taste; his taste is vitiated by sin, and not being changed, sin is a sweet morsel in his mouth, and he disrelishes everything that is spiritual; but one that is born again savours the things of the Spirit of God; sin is exceeding sinful to him, and Christ exceeding precious; he, and his fruit, his promises, and blessings of grace, his word and ordinances, are sweet unto his taste: and the taste he has is not a mere superficial one, such as hypocrites may have of the good word of God, and the powers of the world to come; but such a taste of Christ, and of his grace, as, by a true faith, to eat his flesh, and drink his blood, and so have everlasting life; such have a saving and experimental knowledge of Christ, an application of him, and his saving benefits to them, a revelation of him in them, so that they find and feel that he dwells in them, and they in him; such receive out of Christ's fulness, and grace for grace, and live by faith upon him, and receive nourishment from him; and of this the apostle made no doubt concerning these persons, but took it for granted that they had had such tastes of Christ, and therefore could not but desire the Gospel, which is a revelation of Christ, and sets forth the glory of his person, and the riches of his grace: and whereas, such as have truly tasted of his grace cannot but desire to have more, and fresh tastes of it; where should they have them, but in his word and ordinances? and therefore, would they grow in grace, and know more of Christ, and taste more of his goodness, it is their interest, as it is their spiritual nature, to desire the Gospel, in the purity and sincerity of it.
