The best way to communicate a thing (almost any thing) is to wrap it in language and send it on its way. But sometimes words aren't needed to express what is meant...and may even get in the way.
I used to date a man who swore my sister and I could carry on entire conversations without speaking, so long as we were within sight of one another. (Postscript: He was correct, not paranoid.) We could indeed communicate wordlessly, often did, and still do to this day.
Because I believe Jesus to be the most profound communicator who has ever lived, I have come to believe in the power of wordless love. The gospels are full of moments of great empathy, grace, truth, beauty, correction, agreement, forgiveness...all expressed by the Son of God without a single word.
He sat down at a well next to a woman of Samaria, his presence speaking a silent invitation before his mouth uttered a sound.
He took clay and spit in it, forming it into a paste and pressing it into a blind man's eyes, his touch conveying a kind, determined desire to heal.
His pores spilled blood in Gethsemane when he ran out of words to pray, each drop beseeching the Father to do what He must do for mercy to be ours.
He exchanged a knowing, wordless glance with Peter in a courtyard, late at night--after his boastful disciple whimpered denial not once, but three times.
He wept for Lazarus. He did not eulogize. His tears said everything, and more.
Post-resurrection, he broke bread with two travelers to Emmaus, silently and powerfully introducing himself as the one broken for them.
He was the master of wordless love, and when all of his preaching and teaching and pleading was done, he surrendered not just language, but life--willingly dying in our place.
Does he love us? Oh, yes. Every little thing he does says so.
But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.(Romans 5:8)
