The LORD God is a sun and shield:
the LORD will give grace and glory:
no good thing will he withhold from them
that walk uprightly.
The Lord is all in all. He provides the light yet protects us with the shields of nature. He gives us work yet provides us sleep as well. He gives us health but allows us to be sick on occasion so we can depend on his mercies. He puts us in families so we can know the joy of acceptance and have empathy for the lonely enough to include them. Every good thing comes from him and the "upright" acknowledge that fact and praise him for what they have and what they can give to others.
