Sometimes my wife and I finish each other’s sentences. In over thirty years of marriage we’ve become increasingly familiar with the way the other thinks and speaks. We may not even have to finish a sentence at all; just a word or a glance is enough to express a thought.
There’s comfort in that—like an old pair of shoes you continue to wear because they fit so well. Sometimes we even refer to each other affectionately as “my old shoe”—a compliment that might be difficult to understand if you didn’t know us well! Through the years our relationship has developed a language of its own, with expressions that are the result of decades of love and trust. 
It’s comforting to know that God loves us with a deep familiarity. David wrote, “Before a word is on my tongue you, Lord, know it completely” (Ps. 139:4). Imagine having a quiet conversation with Jesus where you’re telling Him the deepest matters of your heart. Just when you’re struggling to get the words out, He gives you a knowing smile and expresses exactly what you couldn’t quite say. How good it is to know that we don’t have to get our words just right to talk to God! He loves us and knows us well enough to understand.
