So, the idea of being an intercessor, I couldn't figure out if that was man-made or from Scripture. Today the phrase "stand in the gap" came to mind and I checked it out:

Ezekiel 22:30 (New King James Version)

³⁰ So I sought for a man among them who would make a wall, and stand in the gap before Me on behalf of the land, that I should not destroy it; but I found no one.

then I checked out all the commentaries on www.ewordtoday.com and was reminded of Abraham praying for Sodom and Gomorrah, Moses praying for Israel when he found them worshipping the golden calf, Phineas the son of Aaron killing the man and thereby staying the hand of God (Num 25:6-15), Jeremiah being told NOT to pray for the people.

So, obviously, there is a time for intercession, God does listen when His people come before Him on behalf of others; BUT do I see it in the New Testament? Many things have changed, the covenant is slightly different, we are now free to come boldly before the throne ourselves, as individuals -- is it that He is now dealing with us singly whereas before it was as a group??? Hmmm... and I also see that now Jesus "ever liveth to make intercession for us" .... is that the other part? We don't have the call to intercede because that is Jesus' ministry?

I know Paul prayed for people, but I can't think of a time in the NT where someone prayed on behalf of someone in the sense of intercession, standing in the gap.... unless I think of Simon (the one who wanted to buy the ability to give the Holy Spirit to people) asking the apostles to pray for him....
