This isn’t about when he walked on water, but when the wave drowned him.
Tim Keller, writing in Jesus the King (emphasis added).
“Jesus was thrown into the only storm that can actually sink us – the storm of eternal justice, of what we owe for our wrongdoing.
That storm wasn’t calmed – not until it swept him away.
If the sight of Jesus bowing his head into that ultimate storm is burned into the core of your being, you will never say, ‘God, don’t you care?’
And if you know that he did not abandon you in that ultimate storm, what makes you think he would abandon you in the much smaller storms you’re experiencing right now?”
