For My people have committed two evils: They have forsaken Me, the fountain of living waters, and hewn themselves cisterns—broken cisterns that can hold no water. (Jeremiah 2:13, NKJV)
Judah forsook Jehovah for idols. He was the God who gave them water for forty years in the wilderness and the land of Canaan, where they took cisterns they had not dug (Neh. 9:25). The false gods gave them no spiritual refreshment, only spiritual death. Christians must be careful to always and only drink from the fountain of living water, who is Jesus Christ, and not the broken cisterns of false teaching, religious error and worldliness (John 7:37-38). Do not forsake the Lord for broken cisterns that can hold no water.
