When I think how great this happiness is, sometimes it is ready to seem almost incredible. But the death and sufferings of Christ make everything credible that belongs to this blessedness. For if God would so contrive to show his love in the manner and means of procuring our happiness, nothing can be incredible in the degree of happiness itself. If all that God does about it be of a piece, he will also set infinite wisdom on work to make their happiness and glory great in the degree of it. If God spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Nothing could have been such a confirmation of their blessedness as this."
