Someone may ask, “Why is it all about Jesus?”
The answer is of course an eternal revelation and mystery.
God is love. Jesus is love.
God so loved the world . . .
He sent Jesus to save mankind . . . to die for the world.
The gospel is God’s love story for the world.
The gospel is beyond human words or explanation.
What God the Father and His Son have done and are doing – and will do for eternity – is beyond human comprehension.
The revelation that God is one – the Father, Son and Holy Spirit – and yet they are separate and distinct Persons . . . is truly beyond our limited understanding.
He is beyond us . . . He is an eternal revelation.
