Hi neelu. As a child of God, you do have authority over the enemy and can command him to take his hands off of them according to the word of God that the seed of the righteous is blessed. Also for this purpose the Son of God was manifested that he might destroy the works of the devil, and you declare this work destroyed in Jesus' name. Then just release the power of God in Jesus' name to their bodies for the word declares that Himself took our sicknesses and carried our diseases. When I pray for someone close at hand, I continue to command and demand the devil to get his hands of the person, for they have been redeemed by the blood of Jesus until there is a manifestation. Depends on whether they are willing to let me continue to pray. I stand in agreement with you in Jesus' name.
