I've noticed some preachers really want people at the altar (which is usually the area at the edge of the stage rather than a padded bench at the front like you might see in a Nazarene steeple house, a raised table for the mass like you see in an RCC steeple house, or a large sacrificial barbecue pit like structure like you see in the Bible).I've seen preachers give really broad-ranging altar calls. They can be as direct as asking everyone to come up to the front and pray. I've heard an altar call for anyone who wanted to be used of God in their life or something like that. One method that doesn't work to well is to ask people to come forward if they are struggling with something, and then, to start listing different sins and throw in something like porn or homosexuality. Mention homosexuality, and people stop going forward for some reason. Oh, the altar call for gays. That's not me. I've seen it done. I thought, He mentioned homosexuality. No one is going forward.
