The word 'baptism' comes from two Greek words which have a cascade of meanings: 'dip', 'pour', 'immerse', 'submerge' and 'overwhelm'. It was a not a specifically religious word; cooks would 'baptise' vegetables as they were immersed in hot water and boiled! Baptism was, however, a Jewish practice of symbolic purification; and it was used when non-Jews wanted to belong to the God of Israel. It expressed the desire to be clean before God. So John baptised people who repented of their sin and wanted God's cleansing.

But the outward symbol of baptism is nothing without the transforming work of the Holy Spirit. John promised that Jesus would baptise those who loved Him in the Holy Spirit. His baptism was not symbolic, but a real inner filling - infusing the depths of the soul with the personal presence of God. That is what happens when people come to Jesus in repentance and faith. Whilst the all-engulfing presence of God will mean punishment for the rebellious one day, it is real purification and sanctification now for all those who have been made righteous by the blood of Christ.

Some people think that baptism by water is salvation: it is not. Salvation is the gift of God to all those who have repented of their sins and welcomed His Holy Spirit to come into their lives. Baptism by water is the outward sign that that has happened. But without welcoming God the Holy Spirit, it is meaningless. Mary welcomed Him, and Christ was formed in her; the apostles did that, and the church was born. To all who believe, God has promised: "But you will receive power when the Holy Spirit comes on you; and you will be my witnesses…" (Acts 1:8). Only the Holy Spirit can change hearts and reset agendas, so that the gospel is shared and the life of Christ is born into people's hearts. So welcome the Spirit every day to guide and empower you as you serve Jesus Christ.
