I am however suggesting that it may have more life in it than we think. I'm all for burying all smelly corpses lying around. But not while they're still breathing. Sure, you can preach for a verdict and call for decision without giving an altar call. There are an increasing number of other 'decision devices' which are working today.
Some speakers invite seekers to meet in a counseling room and have good results.
Others call on people to raise their hand or sign a card. Recently more preachers invite those with spiritual needs to simply glance up and catch the speaker's eye. These methods are not wrong. In fact, as a guest speaker, I sometimes invite people to lift a hand to indicate to the pastor that they want an appointment to talk about spiritual things. I make sure the pastor makes a list.
