And you, my child, will be called a prophet of the Most High; for you will go on before the Lord to prepare the way for him, to give his people the knowledge of salvation through the forgiveness of their sins,
because of the tender mercy of our God, by which the rising sun will come to us from heaven to shine on those living in darkness and in the shadow of death, to guide our feet into the path of peace."

A theology can contradict Gods revelation. The test is do we change our views and ways to accept Gods ways or insist we are right and scripture is wrong. This is the eternal question, is Christ truly dwelling in us, or are we from a different Kingdom.
