I had a professor in college who asked the class if we were whelmed--not overwhelmed or underwhelmed but just whelmed. He wanted to make sure that the assignments were challenging but not exasperating.
God wants us to be whelmed too--not overwhelmed or underwhelmed. He gives us the right level of difficulty of assignment so that we can be successful through Him.
I am whelmed--not over or under--but just whelmed.
