The longer I live, the more I am convinced that we just don't know what we need. I mean we just don't know what we *really* need, what our needs *truly* are.
That's just one reason why it's so important to trust God's Word, when it says, "...my God shall supply all your need according to His riches in glory by Christ Jesus."
If we ever think our needs are not being supplied, then we simply don't know at that time what our needs really are. But our loving God does, and He has promised to meet them.
