“Though an army encamp against me, my heart shall not fear; though war arise against me, yet I will be confident” (v3). The psalmist knew that no army or outward enemy could defeat him, because God was his stronghold (v1). The real challenge was the waywardness of his own heart; the key to security was “dwelling in the house of the Lord,” staying close to God, and seeking His face (v4,5,8). He prayed: “Teach me your way Lord … because of my enemies” (v11).
“Wait for the Lord … let your heart take courage” (v14). We can be completely confident that God desires to strengthen and protect us, from the inside out.
