John 14:7-9 — If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him. Philip saith unto him, Lord, shew us the Father, and it sufficeth us. Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father? 
Who’s the person that you know best of all? For me, of course, it’s my lovely wife Myra. So, think about that person, that one that you know better than anyone else. How well do you really know that person? Do you know the history that has scarred them, or the dreams that urge them on? Do you know the inner chambers of their heart — the secrets they guard so carefully?

In a way it’s miraculous to me that we manage to relate to each other at all. How do we manage to bridge the gaps? The truth is, of course, that some of us barely do — and none of us do it consistently well all of the time. If it’s so hard to relate to people we see every day, how do we relate to someone we have never seen? How can we manage to relate to God? That’s what Jesus is talking about.

“Hang on a minute”, I hear you saying, “I haven’t seen Jesus, either”. But you have. Some of my favorite verses tell the story …

Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. (Matthew 25:34-36)

Every time we see an unanswered need, we see Jesus. But it’s more than that. Every time we see someone answering one of those needs, we’re seeing Jesus in action. Even when we catch ourselves in need or answering someone else’s need we see Him too.
Seeing Jesus is a learned skill.  We have to look for Him. When we see Him we see God too. That’s how we build a relationship with Him. Learning to watch and see Him at work we get to know who He is. He’s not that hard to relate to.
