The commands of the Gospel are nothing else than God’s lessons, the foundations on which to build up hope, the supports for strengthening faith, the food that nourishes the heart. They are the rudder for keeping us on the right course, the protection that keeps our salvation secure. As they instruct the receptive minds of believers on earth, they lead safely to the kingdom of heaven… Now we are enlightened by the light of grace, and are to keep to the highway of life, with the Lord to precede and direct us.
–Saint Cyprian of Carthage (c. 200-258)
