According to God's command, Deuteronomy 6:6, and promise, Hebrews 8:10. His thoughts, and meditations, and affections are fixed upon it. He doth not talk religiously in design, or with ostentation, but out of the abundance of his heart, Matthew 12:35. None of his steps shall slide: this passage describes either,
1. His safety, consequent upon his piety; God will uphold and preserve him from falling into that mischief which wicked men plot against him. Or rather,
2. His virtue or piety; which is evidenced by his words, Psalms 37:30, by his heart, in the former part of this verse, and by his actions, in these words. His steps or goings (i.e. his actions) shall not (or rather, do not; for this verb, though future, may and should be rendered by the present, as futures frequently are in the Hebrew language, and as the two foregoing future verbs are rendered, Psalms 37:30) slide, or slip, or swerve, to wit, from the rule, or from God's law; which is to be understood as that passage, Psalms 99:3, They do no iniquity, and some such expressions, not simply and absolutely, as if all good men were sinless; which is abundantly confuted, both by many scriptures and by universal experience; but comparatively, and in respect of his design, and course, or custom. His conversation is ordinarily regular and unblamable. He not only begins well, but constantly perseveres in God's ways, and will not be drawn to forsake God and religion upon any terms.
