Psalm 67 is a psalm which confirms that it is God’s plan for the Gentiles to be part of his church/share in the blessings of Christ’s work. It also emphasizes the need to help fellow believers with material gifts and share that which God has given with others. This would be an ideal song to sing in response to your sermon.

19 Now those who were scattered because of the persecution that arose over Stephen traveled as far as Phoenicia and Cyprus and Antioch, speaking the word to no one except Jews.
