Our heart is not turned back, neither have our steps declined from thy way;
Ver. 18. Our heart is not turned back] Metaphora a stadio, saith Vatablus. As those that run a race stand not at a stay, much less turn back again; so neither have we either stopped or stepped backward, but advanced still toward the mark, having Nondum metam, We have not yet attained, for our motto, as St Paul had, Philippians 3:12; being in nothing terrified by our adversaries, nor afraid with any amazement, Philippians 1:28 1 Peter 3:6 .
Neither have our steps declined] We have watched over every particular action; God's people are best when at worst.
