Doubt over what may happen in the future debilitates us. Dread over potential crises hinders clear thinking and decisive decision-making. Anxiety and fear harm one’s faith in God (Phil. 4:4-7). David’s life was being threatened by King Saul when he wrote Psalm 57 and hid in a cave from his would-be assassin (1 Sam. 22:1). Yet, David did not trust in himself or doubt the Lord. “Be merciful to me, O God, be merciful to me! For my soul trusts in You; And in the shadow of Your wings I will make my refuge, until these calamities have passed by” (Ps. 57:1). God’s mercy is higher than the heavens, and His truth touches the clouds, even as His glory fills the earth (Ps. 57:11-12). Instead of doubt, dread, anxiety, and fear, David trusted God’s mercy, justice, and power in times of trouble. For instance, “My heart is steadfast, O God, my heart is steadfast; I will sing and give praise” (Ps. 57:7). Even so, evil lurks nearby and pursues our souls (1 Pet. 5:8). God is merciful to forgive our transgressions as His truth guides our path and executes justice (1 John 1:5-9; 1 Pet. 4:17-19). Let us repent of doubt, dread, anxiety, and fear and replace them with faith in God’s mercy, praise for His steadfastness, and reliance on His truth to vindicate the righteous (2 Thess. 1:3-8).
