Thanks for the consideration. I have some multiverse cards already. I've experimented with putting the references in the reference field, or putting them in the topic field. I've also played with spacing between the references to get them to line up on separate lines. For example:
God Loves You
John 3:16, Luke 19:10, Romans 5:8, Galatians 1:4, 1 John 4:10
Passage field:
John 3:16
| [16] For God so loved the world
that he gave his one and only Son,
that whoever believes in him
shall not perish
but have eternal life.
Luke 19:10
| [10] For the Son of Man
came to seek
and to save the lost.
Romans 5:8
| [8] But God demonstrates his own love for us in this:
While we were still sinners,
Christ died for us.
Galatians 1:4
| ...Jesus Christ,
[4] who gave himself for our sins
to rescue us from the present evil age,
according to the will of our God and Father,...
1 John 4:10
| [10] This is love:
not that we loved God,
but that he loved us
and sent his Son as an atoning sacrifice for our sins.
