John Wesley on Exodus 33:17

I will do this thing also that thou hast spoken - See the power of prayer! See the riches of God's goodness! See in type the prevalency of Christ's intercession, which he ever lives to make for all those that come to God by him! And the ground of that prevalency, is purely in his own merit, it is because thou hast found grace in my sight. And now God is perfectly reconciled to them, and his presence in the pillar of cloud returns to them.
