The root of my joy is Jesus. He can be your joy, too. Independent of your background, your family, your mistakes, or your failures, you are invited! Jesus already loves you; you just need to invite him into your life.
So reach out and welcome one another to God’s glory. Jesus did it; now you do it! Jesus, staying true to God’s purposes, reached out in a special way to the Jewish insiders so that the old ancestral promises would come true for them. As a result, the non-Jewish outsiders have been able to experience mercy and to show appreciation to God. Just think of all the Scriptures that will come true in what we do! For instance: Then I’ll join outsiders in a hymn-sing; I’ll sing to your name! And this one: Outsiders and insiders, rejoice together! And again: People of all nations, celebrate God! All colors and races, give hearty praise! And Isaiah’s word: There’s the root of our ancestor Jesse, breaking through the earth and growing tree tall, Tall enough for everyone everywhere to see and take hope! Oh! May the God of green hope fill you up with joy, fill you up with peace, so that your believing lives, filled with the life-giving energy of the Holy Spirit, will brim over with hope! (Romans 15:7 MSG)
P.S. Jesse is the father of David, the first king of Israel (i.e., the David of David and Goliath). Jesus’ earthly father, Joseph, was a descendent of David. Hence, the “root of Jesse” is referring to Jesus.
