But the word is very nigh unto thee,.... In the ministration of it by those who clearly, plainly, and faithfully preach it, and in the application of it by the Spirit of God to the heart; and in the gracious experience converted persons have of the power and efficacy of it in them, and of the comfort they receive from it: in thy mouth, and in thy heart, that thou mayest do it; in the mouth by confession, being not ashamed to own it, and profess it before men; and in the heart, where it is come with power, has a place, and works effectually, and is cordially believed, and comfortably experienced; and when this is the case, its ordinances will be faithfully kept as delivered, and cheerfully submitted to.
