Matthew 28:18-20 (NIV)

Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”

Romans 6:3-4 (NIV)

Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death?  We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.

2 Corinthians 5:17 (NIV)

Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!
