Notice where David turns in Ps. 34:4–he sought the Lord. David goes to the only source of help when our souls are weighed down with fear. How quickly and comprehensively we cast our cares upon the Lord and his truth is determinative of how faithful we will be in a circumstance. If we spend our time worrying or complaining or trying to manipulate or maneuver our way out of the circumstances, we will not obtain the necessary clarity we need in our hearts to give God the glory he deserves.
As David continues on in v.4, the outcome of him seeking the Lord led to the Lord answering him, primarily in the form of delivering him from ALL his terrors (stronger word than the household fears). So, because he wholeheartedly sought the God of peace, that God brought complete peace to David’s heart. This is very similar to what the Psalmist writes in Ps. 123: 1 To You I lift up my eyes,
O You who are enthroned in the heavens!
2 Behold, as the eyes of servants look to the hand of their master,
As the eyes of a maid to the hand of her mistress,
So our eyes look to the Lord our God, Until He is gracious to us.
So what are the fears that persist in your heart?—”Will this circumstance ever get better? Will this person I’ve been pouring into and praying for ever bear definitive fruit of possessing the Spirit of God?” The question becomes: What do you need to do to seek the Lord with those fears in order to be delivered from them?
