What does Psalm 18:46 mean?
Pagans worship false gods. Then, as now, those imaginary beings were lifeless. Jeremiah describes them as idols that "are like scarecrows in a cucumber field, and they cannot speak; they have to be carried, for they cannot walk" (Jeremiah 10:5). Then he describes the true God. "There is none like you, O LORD; you are great in might" (Jeremiah 10:6). He further describes the Lord as "the true God; he is the living God and the everlasting King" (Jeremiah 10:10).David worshiped this living God and proclaimed Him as his "rock." He exalted the Lord as the God of his salvation (Psalm 18:46). David knew by experience that the God of the Bible is real and powerful; it was this God who rescued David from all his enemies (2 Samuel 22:1). David also knew that the Lord was the source of his safety and security.
This same living God is the believer's God. Through Jesus Christ, His Son, God delivers the believer from sin and eternal death and keeps him safe from the Devil's clutches (Colossians 1:13–14; 2 Timothy 4:18). As believers, we ought to exalt Him as the God of our salvation!
