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 Ceux qui avaient été dispersés par la persécution survenue à propos d'Etienne allèrent jusqu'en Phénicie, dans l'île de Chypre, et à Antioche, annonçant la parole seulement aux Juifs.
