God’s people had allowed idol worship to infiltrate into their way of life. Soon they had a place to worship their idols on every high hill and under every green tree. 
Sin is like that. It takes over every part of your life, including the places that had been flourishing in the Lord. 
Choose to completely abstain from sin before it creeps into areas you hadn’t intended to give. 
Scripture taken from: I Kings 14:21-24
