“The fear of the Lord is the beginning of knowledge; fools despise wisdom and instruction.”
This verse is actually for those unbeliever who think of themselves as wise since they are not for them to believe without scientific explanation or simply faith. It is like Solomon the wisest man (1 Kings 4:30 ) anticipated that this going to happen from those man who believe to be wise.
Even me, I questioned about God’s existence without fearing him before and I believe in myself that I’m wise because I’m not that easy to believe on things that I can’t see. But thanks God as He unfolded himself to me and that is the beginning of my true knowledge, I started to fear Him.
