It’s not enough to love the same person.

1 Thessalonians 3:11-13 

The disciples each loved Jesus, but Jesus was burdened that they would love each other. The Thessalonians loved Paul, but he was burdened that they would grow in their love for each other. A love that travels vertically must also travel horizontally. Loving others is the mark of an authentic love for God, and it is the sure indication that our faith is maturing.
