Abijah v. Abijam and staying accountable to true worship

1 Kings 15 introduces us to Abijah, Rehoboam's son and successor to David's throne.  The NIV calls him Abijah to match his story in 2 Chronicles 13.  The ESV calls him Abijam.  Abijah means "my father is YHWH", and Abijam means "my father is the sea."

The 1 Kings account shows a wicked king who followed after the idolatry of his father, and the name Abijam would more reflect the pagan leanings of Rehoboam and his son.  The 2 Chronicles account gives a story of a man who was attacked by Jeroboam but rebuked him and all of northern Israel for turning away from the worship of the true God and setting up golden calves and pretending to worship him.  So which man do we have?  Do we have Abijah who loved God's glory or do we have Abijam who fooled around with idols?

Since both accounts are in the Bible, and the Bible is all true, then both accounts are true somehow, but I'm not sure how.

Just like the Bible shows a Rehoboam who was foolish in his young days and caused the kingdom to split, but then humbled himself when a prophet told him to stop attacking the north, but then still had constant warfare with the north, the inspired Scriptures also show a much compromised Abijah.  Maybe he grew up in a compromised religion where he could worship God one day but then play with the world on other days.  Perhaps when he was older and could no longer take the constant warfare with Jeroboam, he came to his senses and rebuked the other king for his apostasy, much like the thief on the cross who repented and rebuked the other thief for mocking our Savior as he was dying.

In the end, I don't know completely how the two accounts jive, but they do somehow.  Much like how God doesn't always make sense in my life, but I know he's good and that he loves me.  One thing is true.  Judah still had the worship of the true God, and Israel abandoned him but pretended that they still worshiped him.  And that accountability of worshiping God on his terms kept the southern kings on David's throne no matter how much their hearts strayed.  In the same way, we must stay with the God of the Scriptures who sent Jesus to die for our sins.  Our hearts will naturally stray from the path, but if we have the accountability of reading the Bible every day and going to church every week, especially when we don't feel like it, the Holy Spirit will be faithful to guide us back to the right way of worship and living.
