Man Plans His Way.
A man's heart plans his way, but the Lord directs His steps. Proverbs 16:9 NKJV
Man is here represented to us, as a reasonable creature, that has the faculty of contriving for himself: His heart devises his way, designs an end, and projects ways and means leading to that end, which the inferior creatures, who are governed by sense and natural instinct, cannot do. The more shame for him if he do not devise the way how to please God and provide for his everlasting state.
But as a depending creature, that is subject to the direction and dominion of his Maker. If men devise their way, so as to make God's glory their end and his will their rule, they may expect that he will direct their steps by his Spirit and grace, so that they shall not miss their way nor come short of their end. But let men devise their worldly affairs ever so politely, and with ever so great a probability of success, yet God has the ordering of the event, and sometimes directs their steps to that which they least intended. The design of this is to teach us to say, If the Lord will, we shall live and do this or that (James 4:14, 15), and to have our eye to God, not only in the great turns of our lives, but in every step we take. Lord, direct my way, 1 Thessalonians 3:11. - Matthew Henry
