He had another option. Once again he was faced with a threat. Israel was building defences against him. He could have sought God like he did when he was younger.
But he decided to rely on his own wit and wisdom…and it worked!
I’m sure he was patting himself on the back for creating his own defence fund building project when Hanani the seer came to him to call him to account.
It could be why he responded the way he did. He was pleased with his choice of option and he was confronted for it.
Look what else happened to Asa after his response to Hanani 2 Chronicles 16:11-14
Note verse 12 – wouldn’t seek God, even in sickness
(Please note, it isn’t saying to not seek the help of physicians…only to not rely on them alone and not God)
