If you are living under the same roof with someone as if you were married, you need to get out of that relationship just as you would get off of a sinking ship. There is no protection for you. You have rendered your ministering spirit, your guardian angel, helpless because you are out of the will of God. You are living on dangerous ground and in a perverted situation. No blessing can come to you.
Marriage is the basis of the home, the basis of male and female relationship.
Therefore, any relationship not functioning in line with the Word of God is sin. It is wrong and opens up those involved to the attacks of demons. There is nothing the Heavenly Father can do, although He might, in His mercy, like to, but He will not protect the areas of your life where sin exists. He cannot protect sin, and if you are in sin, you are outside God's protection. His power operates within the framework of His revealed Word.
