The Christmas carol Joy to the World gives us and understanding of what the gospel can be for those who haven’t gotten in on Jesus-type joy.
The song starts with “preparing Him room” (Isa 40:3-5; Jn 14:1-4; 16:7, 13)
The second verse call out to all people to join the universe in a new song of joy (Ps 98:1- 2; 96:1-2; 149:1b; Isa 42:10-11a.
The third verse speaks of reversing Adam curse (Gen 3:17-19). 
And the final verse points toward Truth, Grace and Love rather than Power, Domination and Control as the source of of Jesus Joy (Lk 22:24-26; Heb 12:1-2a).
