Jesus could endure the storm because he claimed his identity repeatedly. In his three years of public ministry, Jesus often got away to pray and centre himself in his identity. He would go off on his own and say,
I am God’s beloved Son. It doesn’t matter what people are saying about me. It doesn’t matter what’s happening to me. I’m going to be faithful. I’m going to love the people God wants me to love. I’m going to do what God wants me to do.
In fact, for Jesus, this started even before his public ministry. In the 30 years leading up to it, Jesus was already establishing his identity. Learning to see himself as God’s beloved son.
If you’re going to make it, you need to claim your identity repeatedly. Lather, rinse, repeat.
