IHOP is an outgrowth of the Kansas City Prophets group. Revival is good, and Spirit-filled revival is wonderful. I highly recommend it. The larger the gathering, the easier to blend into the crowd and experience what God has without being noticed. Let God move in you and fill you. After all, who can deny water to those who have the Holy Spirit as do the rest? That was Peter's argument in Acts, I believe. Claim it.
One caution: don't get caught up in the prophetic, especially when it involves forecasting the future of nations, including Israel. Most of these ministries are Zionist and can get quite fanatical. Better to let God fill you and use you to minister to others, as the great commission directs. The true prophetic ministry to the body is to edify, encourage, and exhort. Rarely to correct and even more rarely to foretell the future.
