Canst not tell whence it cometh

The bible includes several passages that emphasize our inability to understand heavenly matters. One example occurs in the book of Judges, when an angel announces to Samson's parents that they will have a son. Samson's dad asks the angel his name, to which the angel replies (Judges 13:18, KJV),

Why askest thou thus after my name, seeing it is secret?

The Hebrew word translated as "secret" means something close to "incomprehensible."

Another example occurs in John 3, when Jesus is dining with Nicodemus. Nicodemus expresses confusion about people being "born again" with the spirit of God. How can that actually happen? Jesus responds (John 3:8, KJV),

The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.

Jesus says that, although we hear the wind, we neither know where it comes from nor where it goes. And the same goes for the spirit of God.

Passages such as these serve to remind us that we should adopt a humble attitude toward spiritual matters. The point of faith is not to understand everything. Rather, the point simply is to believe and trust in God.
