We start early in life trying to express our love. It may be a hug and a kiss or a bouquet or a poem. Entire industries have been built on helping people to express love.
As kids, we already had it figured out: Jesus said, "If you love me, you will obey what I command." (John 14:15) This isn't strict legal test where if you don't obey then you must not love. Rather, it's a truth known deep in our hearts. If we love someone, don't we wish to please him/her?
What I miss most about the trip was knowing every minute of every day that I was expressing that love. I woke up in a foreign bed expressing that love. I ate strange (to me) foods expressing that love.
Back in this world, actions and thoughts with the purest intentions still leave room for doubt. How I miss the simplicity of those days...
