Today is Pentecost Sunday.
When they heard this, the people in the crowd were cut to the heart.
‘Brothers,’ they said to Peter and the other apostles, ‘what shall we do?’
‘Turn back!’ replied Peter. ‘Be baptised – every single one of you – in the name of Jesus the Messiah, so that your sins can be forgiven, and you will receive the gift of the holy spirit. The promise is for you and for your children, and for everyone who is far away, as many as the Lord our God will call.’
Acts 2:37-29, New Testament for Everyone
