Aside from Jesus' talking with the Father during the night before his arrest in the garden, is there any other biblical warrant for extended prayer sessions? I can remember that our church scheduled a 24-hour season of prayer prior to a revival. We all signed up for one-hour increments. When my hour came, I had run out of things to pray about after about 10 minutes. I have heard stories of people praying for an extended period of time "until the answer came." At the same time, why can't we just take our burdens to the Lord and leave them there? God obviously doesn't need long prayer sessions, He already knows what we want. So, those of you who have been involved in such prayer sessions, I'd like to hear about them.
