Healing in Proxy

I have a little testimony to share here. Got a word of knowledge that led a friend asking for healing prayer of headache. Though we were in different locations, but I went ahead to command it to leave. First prayer not much effect. So I stood up to declare the healing again, and I heard the Holy Spirit saying stand in proxy for him to receive that healing as though praying for myself! After that prayer, a minute later, this friend text me again saying the pain has gone! Wonderful? Amazing & amazing because I never stand in proxy to receive healing and being the one praying at the same time! And it works! Woohoo! Praise the Lord! =)
