Jeroboam is just a wicked king. God sends a prophet out to him. This prophet gives a weird (okay I think it's weird) prophecy.
And behold, a man of God came out of Judah by the word of the LORD to Bethel. Jeroboam was standing by the altar to make offerings. 2 And the man cried against the altar by the word of the LORD and said, "O altar, altar, thus says the LORD: 'Behold, a son shall be born to the house of David, Josiah by name, and he shall sacrifice on you the priests of the high places who make offerings on you, and human bones shall be burned on you.'"3And he gave a sign the same day, saying, "This is the sign that the LORD has spoken: 'Behold, the altar shall be torn down, and the ashes that are on it shall be poured out.'"Jeroboam wasn't impressed by this.
4And when the king heard the saying of the man of God, which he cried against the altar at Bethel, Jeroboam stretched out his hand from the altar, saying, "Seize him." And his hand, which he stretched out against him, dried up, so that he could not draw it back to himself. 5The altar also was torn down, and the ashes poured out from the altar, according to the sign that the man of God had given by the word of the LORD.The king wanted his hand healed (go figure that eh?) :) so the prophet when asked nicely by the king, entreated the Lord God to heal his hand. God did! Now that would have been awe-inspiring to see wouldn't it?
Now here's the part where you start seeing what obedience is or isn't....
7And the king said to the man of God, "Come home with me, and refresh yourself, and I will give you a reward." 8And the man of God said to the king, "If you give me half your house, I will not go in with you. And I will not eat bread or drink water in this place, 9for so was it commanded me by the word of the LORD, saying, 'You shall neither eat bread nor drink water nor return by the way that you came.'" 10So he went another way and did not return by the way that he came to Bethel.And then disobedience:
11Now an old prophet lived in Bethel. And his sons came and told him all that the man of God had done that day in Bethel. They also told to their father the words that he had spoken to the king. 12And their father said to them, "Which way did he go?" And his sons showed him the way that the man of God who came from Judah had gone. 13And he said to his sons, "Saddle the donkey for me." So they saddled the donkey for him and he mounted it. 14And he went after the man of God and found him sitting under an oak. And he said to him, "Are you the man of God who came from Judah?" And he said, "I am." 15Then he said to him, "Come home with me and eat bread." 16And he said, "I may not return with you, or go in with you, neither will I eat bread nor drink water with you in this place, 17for it was said to me by the word of the LORD, 'You shall neither eat bread nor drink water there, nor return by the way that you came.'" 18And he said to him, "I also am a prophet as you are, and an angel spoke to me by the word of the LORD, saying, 'Bring him back with you into your house that he may eat bread and drink water.'" But he lied to him. 19So he went back with him and ate bread in his house and drank water.
Did you catch that? The old prophet lied to him. BUT since the man told the younger prophet that God told him to come, he went. He disobeyed God.
Have to admit...once I caught that it was like "oh". Just because someone says they are of God doesn't mean that they are. When God tells us to do something, and we know clearly that HE is the one telling us to do something, then we must needs follow it, REGARDLESS of what others says about it. They might be lying too!
