In response to Peter’s explanation of the coming of the Holy Spirit – the people are cut to the heart and ask the apostles “Brothers what shall we do?” Peter’s answer comes in a four piece package, like four legs of a stool. 1. Repent (turning our lives back to God) 2. Believe (have faith) in the name of Jesus 3. Be baptised in water 4. Be baptised in the Holy Spirit. As we read through Acts we’ll see these four aspects of salvation coming into real people’s lives, displaying God’s amazing grace time and time again.
