Age of Accountability, Too Many Churches, and Healings

Today the "Classic Crew" is back with more questions to be answered. What is the "Age of Accountability?" Do Jewish customs inform us with regard to our Christian faith on this topic? Second, how many churches should someone attend? Is it okay to attend many churches, or should you eventually "settle in" at just one? Lastly, what are we to make of "prophetic healing" or "deliverance" ministries? Where is the line between "praying for" vs. "preying on" the sick or disabled?
