Psalm 64:1 Hear my voice, O God, in my prayer; preserve my life from fear of the enemy.
In his distress, David prays to God to hear his voice and preserve his life from fear of the enemy. In our own lifetime on earth our spiritual enemies, Sin, Death, and the Devil, scare us with all kinds of threats and attacks. When we sense what is going on in the spiritual world of our soul we realize that enemies are scaring us to be afraid, to doubt, to be anxious, and to worry. That is a signal to lift our voice in prayer to God. We respond to impending trouble by turning to the Lord, asking Him to preserve the soul from fear. “Deliver us from evil.”
We will not turn away from God at the first sign of bad things; instead, we turn toward the Lord. And He preserves us from fear, doubt, and worry. Our sin has turned God away from us (“your sins have separated Me from you”). But God loved us still and sent His Son, so that because of Christ God now turns toward us. He hears our prayer and preserves from fear. So we fear, love, and trust God alone.
