Why did those people appreciate more the praise from men, rather then the praise from God, in John 12:43?
When we do not have a proper relationship with God, and do not know him personally, we will look more for the praise of men.
Those who know God on a more intimate level, will for praise from him.
When we are concerned more with what people will say about us, rather then what God will say about us, we want the praise and approval of other people for us.
The only way for us to be more concerned about what God will say about us, is if we have a proper personal relationship with him, and know him personally.
