Psalms 73:9

"They have set against Heaven their mouth, and their tongue hath passed over above the earth" (ver. 9). For this, "hath passed over above the earth" is, they pass over all earthly things? What is it to pass over all earthly things? He doth not think of himself as a man that can die suddenly, when he is speaking; he doth menace as if he were alway to live: his thought doth transcend earthly frailty, he knoweth not with what sort of vessel he is enwrapped; he knoweth not what hath been written in another place concerning such men: "His spirit shall go forth, and he shall return unto his earth, in that day shall perish all his thoughts." But these men not thinking of their last day, speak pride, and unto Heaven they set their mouth, they transcend the earth. If a robber were not to think of his last day, that is, the last day of his trial, when sent to prison, nothing would be more monstrous than he: and yet he might escape. Whither dost thou flee to escape death? Certain will that day be. What is the long time which thou hast to live? How much is the long time which hath an end, even if it were a long time? To this there is added that it is nought: and the very thing which is called long time is not a long time, and is uncertain. Why doth he not think of this? Because he hath set against Heaven his mouth, and his tongue hath passed over above the earth. "And full days shall be found in them."

"They have set their mouth against heaven, and their tongue has passed over the earth." We learn the meaning of "to set one's mouth against heaven" from the younger of the two brothers, who returned to his father and said, "Father, I have sinned against heaven and before you." But those who think that freedom to sin is given to them by some inevitability of birth are setting their mouth against heaven. Such people usually spare neither heaven nor earth, that they may believe that people's lives are governed by the course of the stars, as it were. They leave nothing to providence, nothing to good character. And would that they also had returned like that one of the two young men—the good Lord would not have denied them a remedy! And yet, even if they do not wish to be healed, the Lord keeps open the option of a return, so that those in Israel who were driven out by the blindness of their own hearts may come back through the fullness of the church. Thus they may spend the days of their lives, not in emptiness but filled with good works and faith, when the Lord has filled them with his spiritual favor. Learn how they may return. "A partial blindness only has befallen Israel, until the full number of the Gentiles should enter and thus all Israel should be saved." But it was fitting that the mystery be fulfilled, that God should shut up all things in unbelief, that is, that he should refute and convict them. (For when two parties contend, if one is the stronger, it is said, "He has shut up the other.")45 And thus, by his mercy, that people indeed went back among the heirs, so that the world might be made subject to God. But they were led astray by the delusion of their late wickedness, so that they would not believe that God had foreknowledge of things hidden. But that they may be redeemed at some time, the Lord has kept open for them the option of future salvation and has said, "Therefore will my people return here." What is "here"? It is "to me, to my equity and justice, to my worship." "And full days will be procured for them." This you will interpret as follows, that the people who have believed are assuredly redeemed. According to this, even though those who have not believed are not redeemed, still the redemption of the people is granted as a special favor of God.
