4. That we must boast in nothing, since nothing is our own.
In the Gospel according to John: “No one can receive anything, except it were given him from heaven.”[1] Also in the first Epistle of Paul to the Corinthians: “For what hast thou that thou hast not received? But if thou hast received it, why boastest thou, as if thou hadst not received it?”[2] Also in the first of Kings: “Boast not, neither speak lofty things, and let not great speeches proceed out of your mouth, for the Lord is a God of knowledge.”[3] Also in the same place: “The bow of the mighty men has been made weak, and the weak are girt about with strength.”[4] Of this same thing in the Maccabees: “It is just to be subjected to God, and that a mortal should not think things equal to God.”[5] Also in the same place: “And fear not the words of a man that is a sinner, because his glory shall be filth and worms. Today he shall be lifted up, and to-morrow he shall not be found; because he is turned into his earth, and his thought has perished.”[6]
