It was discussed here as well :

I do not believe altar calls should be practiced.
1. They are not prescribed or described in Scripture. Practices in worship must be Biblical or else they don't belong. I'm an odd bird - I believe the Bible :laugh:
2. They make Baptism into something foreign to the NT. in the NT, the baptismal event was the public testimony of a conversion. In the modern Baptist church, walking an aisle is. How messed up is that?
3. They open the door for relying on human faculties rather than on the Holy Spirit to bring about the work of conversion.
4. They are indicative of a poor theology of savlation/soteriology.
It is interesting to note that since altar calls became prevalent in baptist churches, many would argue we've seen a downgrade and easy believism creep in, along with unregenerate membership.
I'm thinking right now of many baptist churches, gospel-centered, who do not give altar calls. they baptize new converts almost every Sunday. I find it interesting that Spurgeon, et.al, never gave them, though they did invite people to come to Christ and had inquiry rooms, etc.
At the end of the day, our practices must come from the Bible. God, not man, is the author of salvation. This is why I think ideally they should not be practiced. But if they must be (because you could preach from the Koran in most Baptist churches but as long as you sing 3 stanzas for an altar call, you're fine) they must be done VERY carefully. But as I said, ideally, churches would be healthy enough to accept the Word and not have them.
