Worship evangelism
Psalm 96, and particularly these verses, paints a wonderful picture of worship evangelism. Our ability to tell people of God's salvation and redemptive work through Jesus Christ should flow out of our lifestyle of singing to the Lord in a new and fresh way every day, blessing His name, and declaring His glory. When we praise God for His greatness, we are empowered by the Holy Spirit to go out and be a witness among those who don't yet know Him. So let's heed the words of the psalmist and sing to the Lord a new song!
