A person’s level of availability says much about their priorities. It’s warming when a friend says “I’m here for you whenever you need me.”
Now imagine your boss said the same thing. “Call me anytime. I’ll make myself available.” That would be astounding. To take it even further, suppose that the mayor were to say “Whenever you need to talk, I’ll stop and make time for you. You’re that important to me.” You’d be floored.
But God, who hand-crafted the universe, has done this for us. We've been given the Holy Spirit; we have perpetual communion with Him. He's promised not to leave and His listening ears never tire.
