Judah’s elite were imitating the idolatrous cultures of the neighboring ungodly kingdoms. Why should God’s people use God’s blessings to imitate the lifestyles of those who hate God?
If I can live without God some of the time, then I can live without Him all of the time: Therefore, I don’t need Him. That is the definition of pride. If I don’t need God, then I am my own God.
Idolatry has no place in the Body of Christ. We cannot lead anyone to Christ if we do not believe in His exclusive lordship over our lives. We cannot lead anyone to faith in Christ if our faith is compromised by idolatry. We cannot be priests of God and serve another “god”.
