12 If I have told you about earthly things and you don’t believe, how will you believe if I tell you about heavenly things? (John 3:12 CSB)

There is much we can learn while on this earth. We may gain wisdom and deep knowledge in various areas of study, or from an occupational standpoint. We may be book smart or street smart. We, each day, have the opportunity to learn something new and now have the knowledge of the world at our fingertips.

But if we come to know everything, but know nothing of heaven, what use would it be?
