What is so important about the baptism of the Holy Spirit? Why does it matter for Christians whether it is a one-time event or not? In this sermon on John 1:16–33 titled “Spirit Baptism and Scripture,” Dr. Martyn Lloyd-Jones examines the difficult issue of the baptism of the Holy Spirit. He says that the baptism of the Holy Spirit is not experienced by all believers, and ought to be distinguished from the indwelling of the Holy Spirit. Examples of what it means to receive the baptism of the Holy Spirit can be seen in the apostles after Pentecost –– they went from being frightened to bold ambassadors for the gospel of Jesus Christ. While not all Christians receive this baptism, all who believe in the gospel are saved and can know the regenerating power of the Holy Spirit. Believing the gospel is of most importance. Dr. Martyn Lloyd-Jones says that one can live and die without ever receiving the baptism of the Holy Spirit and enter the kingdom of God. Yet if one does not believe in the gospel, they will not be saved.
