What does the Bible say about the division between true and false religion?

In 2 Chronicles 13, we see the division within Israel represented by two kingdoms: the northern kingdom under Jeroboam, a figure representing all false religion, and the southern kingdom led by Abijah, symbolizing the true church. This scripture illustrates the deeper truth about the gospel of God's grace and the insidious nature of false religion, which often caters to human desires and convenience rather than honoring God's prescribed means of worship. The division between true and false religion is ultimately grounded in the choice to worship the true God as He has revealed Himself versus creating gods that are convenient or palatable to our own understanding and desires. This ongoing struggle reflects the broader biblical narrative where sin causes separation from God, highlighting the importance of clinging to the gospel of grace in Christ alone.
