What does Psalm 14:7 mean?
David longs for the ultimate deliverance of Israel. This psalm has noted the arrogance and ignorance of wicked people (Psalm 14:1), who oppress and harm godly people (Psalm 14:4). Yet, David knows those who reject the Lord will face the terror of His judgment (Hebrews 10:31; Psalm 14:5).When Jesus returns to establish His kingdom on earth, He will vanquish His enemies (Revelation 19:11–16), cleanse Israel of her sin (Zechariah 13:1), and inaugurate the kingdom (Zephaniah 3:16–20). Isaiah comments in Isaiah 12:2 that Israel will confess in that day: "Behold, God is my salvation; I will trust, and will not be afraid; for the LORD GOD is my strength and my song, and he has become my salvation." Isaiah also comments, "With joy you will draw water from the wells of salvation" (Isaiah 12:3). David anticipates the kingdom as a joyful time of restoring Israel's fortunes.
The apostle Paul writes in Romans 11:26–27: "And in this way all Israel will be saved, as it is written, 'The Deliverer will come from Zion, he will banish ungodliness from Jacob'; 'and this will be my covenant with them when I take away their sins.'"
