Sometimes advice is given that we don’t trust because the person given the advice can’t understand why we feel the way we do.
Rebecca Reynolds observes that Jesus is different.
He tells us, and he knows exactly how and why we feel as we do.

When the Bible speaks about fear – which is often – it speaks into all of this complexity. God knows your defaults. He knows your instincts. He knows your biology, your chemistry, your genetics, your experiences, and your intellectual capacity. Every connection that occurs in your nervous system, every fluid released by every gland, every physiological reaction – from the lump in your throat to the drop of your stomach – is seen by the God who made you.
This means that when Jesus comes to the believer saying, “Do not fear,” he’s not like humans who tell you not to worry. He understands what others cannot understand about us because he knows us back and forth, inside and out. He knows that for some of us, this is a command to walk on land, and for others it’s a command to walk on water.
