“Behold, God is my helper; the Lord is the upholder of my life” (Psalm 54:4, ESV). Psalm 54 emphasizes God’s power to protect against the schemes of the wicked. David calls out to the Lord for rescue from the hands of those who conspire against him (vv.1-3). Verse 4 is the hinge, where the psalm turns from petition to confidence in God’s protection (vv.4-5); the expectation of grateful worship follows (v.6), built on assurance of God’s salvation (v.7).
You are not alone, whatever you may face. Christians have the greatest possible comfort in this life, knowing that God Almighty cares for them and will carry them through every danger, and shield them from every fear. Take heart, and trust in the Lord.
