The story of Ahaz king of Judah. He had a good father (2 Kings 15:32-38) to show him the right way of the Lord. He is a picture of believers who stubbornly refuse to change their ways to conform to the Word of God (See Hos. 4:17). A person who persists in following his own way, is often led away into worse error. This king is an example.
V.10-18 Ahaz, king of Judah, goes to visit the king of Assyria. But God wants His people to keep separate from those people who worship idols. Notice what appeals to his eyes! He prefers this altar to the one which God had designed (Ex. 27:1-2). Did this please God? Of course not. Many believers today think that it is perfectly correct to learn a bit from different religions. Denominations which borrow from Judaism and the other religions are doing this. Pray that our eyes might be opened to see the errors into which Satan is leading many believers. All done to rob the Lord Jesus of the glory He deserves.
