Salmos 143

Salmos 143:2
But if someone asks why God predicted all the things predestined and still did not promise all the predestined things, we answer that it cannot be called a promise unless when it is predicted that something is going to be done, what is done can be of use to the one to whom it is promised. What is promised is always something of a gift but not always something of a judgment, since the gift of what is promised always brings happiness while the severity of a judgment sometimes saddens.As the prophet, fearing something of this sort, pours out his prayer to God: "Do not enter into judgment with your servant, for no one living is righteous before you." For he knew that all would have to be restrained by the equal chain of punishment unless God, in those whom he willed, made mercy surpass judgment. Justification and glorification that do not exist in a human being from a human being, but from God, have been both predicted and promised because they were to be of great benefit to the saints. — LETTER TO MONIMUS 1:25.1-2
