Jesus spent the whole night praying before he called the twelve disciples to journey with him. He had a big decision to make.
He had to choose the 12 that would not only walk with him for the three years of his earthly ministry, but they would be the torch bearers for the future of the Christian faith. A ten minute prayer just would not cut it.
It was a deep, long, drawn out conversation with God. How can we get past the business of our lives to pray like this?
