An altar call is a public invitation extended by a Christian preacher or evangelist at the end of a worship service or event for people to respond to the Gospel message. It typically involves an invitation to come forward to a designated area, such as the front of the church or stage, to publicly acknowledge a decision to follow Jesus or to receive prayer for a specific need. Altar calls are a longstanding tradition in many Christian denominations and are intended to provide a clear opportunity for people to make a commitment to Christ and to receive support and encouragement from the church community. While not a necessary or universal part of Christian worship, altar calls are seen by many as a powerful and effective means of evangelism and spiritual growth.
