Relating eyes to sight

Yesterday I happened to have two separate conversations about sight. First was a question I get pretty often: How do I have a relationship with someone I can't see? (Jesus, for instance). And the second was a question about Ephesians 1: What does Paul mean by 'the eyes of your hearts'?

It occurs to me that the answer to question two might also be a good answer to question one. The 'eyes of our hearts' refers to our imagination and understanding. Genuine relationship—even with people we can 'see'—is so rich with imagination and understanding (experience). It hardly depends on physical sight at all.

On this basis, we're at almost no disadvantage to Jesus' first disciples. And like any genuine relationship, the more time we spend with Jesus, the narrower the gap between our imagination and our understanding (experience).
