For over confident in blaming everything bad on the Devil, they cannot answer this correctly: Can Satan fake God's blessing?
Consequence:
1. Irresponsibility: e.g. As long as I see myself blessed and not see other people being hurt, God is good!
2. Pride: e.g. I must tell others how God has blessed me, because I know others don't have the same experience.
3. Selfishness: e.g. I don't know nor care how God has blessed others, but I will make it clear to everyone how God has blessed me.
And the list goes on...
