My real feelings are that the oil and laying on of hands is not going to hurt. If it comforts someone, super. If, however, you claim this literally does something, hmmmmm. Making God too much in our lives reduces Him/Her to arbitrary, i. e., who should be healed. Too much of a problem.
If I were back with a congregation now and thank the Lord, I'm not, I would be wanting them to deal with the Gaza conflict, the Biblical interpretation of all of this, i. e., did God really give the Jews this land? And, how literal can we deal with the Old Testament with the Christian idea that God will always do what is right.
