A group without a leader usually drifts off into the mists. So it is important to have someone take responsibility for leading the group. It's hard to lead when a thousand other things demand your atttention. I don't even object much to a 'spiritual warfare ' view of intercessory prayer, taken in the right way. But spiritual warfare is not the heart of intercessory prayer, nor are strategies for victory.
Intercession is a matter of love first, beyond anything else.
It is a matter of perspective, looking outward from ourselves to see the torture that life can become for other people, and being moved by it. The Devil loses when the Spirit builds people up through praying and being prayed for. Spirithome has more on healing , health and what Christians are and have been doing to stand with and for the ill. Lip service does nothing for God. He prayed for His enemies, and you do not even pray for your friends.
