The Bible talks about missionary work on many occasions, e. g. , in Matthew 28:19-20 ("Go therefore and make disciples of all nations"), with a similar fragment in Mark 16:15, quoting Jesus ("Go into all the world and proclaim the gospel to the whole creation"). You can further consider 2 Corinthians 5:20, Luke 14:23, Luke 24:47-48, Acts 1:8 and Acts 26:18.
