He (God) satisfies the desire of every living thing, except the unreasonable children of men, who are satisfied with nothing. Matthew HenryAre you satisfied with nothing, or are you praising the Creator for everything he has given you?
I think Matthew Henry must have been thinking about the Israelites after the Exodus. Nothing satisfied them for long. Rather than praising and blessing God, they grumbled. They wanted meat instead of manna. Quail didn't make them happy either. 40 years in the wilderness is what it took to make them change their attitude.
Attititude is key to being happy.
When you believe that all things come to you through God, your attitude should be one of praise and thankfulness. Happiness is being thankful for what God has done for you.
