My impression would be to pray for the indiviual that he receives Christ and after that let Christ do His work in the person's body . God is able to interviene in things and situations that we think are impossible cause He deals with the impossible . OUr mandate is to pray and intercede on behalf of others . Prayer changes things . Satan has no power over the righteous prayers of the saint .let me put it a diffrent way,a devil cult trying to inflict pain on people who have not found Christ yet.lets say the klu klux klan.one of there members is sick as the result of his own evil.you wouldn,t pray his leg gets better or his body is mended,you would pray he finds Christ.like anything else in this life satan can turn things to his advantage.
No one knows more than Jesus, except the Father alone..so you know better than jesus.?
Thank you Who Am I.
