Worship and witness flow together. David understood this as revealed in 1 Chronicles 16. David presented a psalm of thanks to celebrate the return of the ark of the covenant to Jerusalem.
A thousand years later in Jerusalem on the day of Pentecost, people from many nations heard the 120 Spirit-filled believers speaking in their own languages “the wonderful works of God” (Acts 2:11). Such powerful praise became the occasion for the Apostle Peter to proclaim salvation through Jesus’ name to those who had come. With worship came witness and three thousand believed in Jesus, were baptized in water, and received the Holy Spirit (Acts 2:38–40).
As those who have also experienced “the wonderful works of God,” let us both “sing to the LORD” and “declare His glory among the nations”!
