Just be careful. The enemy LOVES using relationships to not only stray people from Satan but to make them weaker and not as dedicated to our cause as well. Its really terrible how they use the most innocent and sensitive parts of humanity against us, but they do, and its like an algorithm of feces. He may seem like the perfect guy to you, but have you seen the movie "The Matrix"? Its like in that movie and you should never doubt how grave it really is. You might want to use runes like JERA and ALGIZ on him and affirm something like "___ is being built a powerful aura with the runes JERA and ALGIZ. He is completely protected from enemy influence and is being influenced by the immemorial nature within to safely and surely find and align with Satan's will."This way at least you can test him. You act as his fate here. Be warned however, Satan will be testing him as well as Satan first acted on your fate to influence his. Everybody goes through testing to make sure of their integrity. You might not expect it but this can end up hurting you pretty badly and end up making you so pissed off that you don't even want them to find Satan anymore because you don't think they deserve it, after betraying your trust so deeply and seeing them infested with spiritual feces. Then, it will only make it harder for them. I know from experience.
