Please don't be ungrateful fools. If God blesses you and you are not thankful for it, are you not being unwise?
Eph 5:17 Therefore do not be unwise, but understand what the will of the Lord is.

Proverbs 19:8 He who gets wisdom loves his own soul; He who keeps understanding will find good.
Proverbs 9:10 The fear of the LORD is the beginning of wisdom, And the knowledge of the Holy One is understanding.
It is the will of God for you know him and be thankful.
