A fatherless, an ordinary official was chosen as a king over ten tribes of Israel. The LORD God Himself promised to Jeroboam. The Lord would like to build him a dynasty as enduring as the one He built for David and would give Israel to him. Even He would humble David's descendants because of this, but not forever. It was a great honor and grace, what a perfect promised blessing that Jeroboam got from the Lord!
"However, as for you, I will take you, and you will rule over all that your heart desires; you will be king over Israel. If you do whatever I command you and walk in my ways and do what is right in my eyes by keeping my statutes and commands, as David my servant did, I will be with you. I will build you a dynasty as enduring as the one I built for David and will give Israel to you. I will humble David's descendants because of this, but not forever." (1 Kings 11:37-39)
Although the Lord had fulfilled His promises when Israel made him king over all Israel, Jeroboam did not stand on His promises. Instead of thanking God and walk in His ways, Jeroboam had his own mind.
Jeroboam thought to himself, "The kingdom will now likely revert to the house of David. If these people go up to offer sacrifices at the temple of the LORD in Jerusalem, they will again give their allegiance to their lord, Rehoboam king of Judah. They will kill me and return to King Rehoboam. (1 Kings 12:26-27)
Jeroboam felt insecure regarding his own throne. He did not realize that his throne was God's given gift. Then no one could take his throne without God's permission. Feeling insecure, Jeroboam did not seek God but advice from his people. Then he made two golden calves to be worshiped, so the Israelites did not need to go up to Jerusalem anymore.
From what Jeroboam did, we can see the danger of not standing on the promises of God.
