Isaiah 30:15

Let us, then, devoutly think over these truths, dearest brothers, while it is still within our power to do so with the help of God. As we shudder at the wounds of our sins as at deadly poisons, let us apply ourselves to almsgiving, prayer …

(Verse 15 and following) For thus says the Lord God, the Holy One of Israel: If you return and rest, you shall be saved; in quietness and in trust shall be your strength. But you were unwilling, and you said, 'No! We will flee upon horses'; therefore you shall flee away, and, 'We will ride upon swift steeds'; therefore your pursuers shall be swift. One thousand at the threat of one; at the threat of five you shall flee. LXX: Thus says the Lord God, the Holy One of Israel: When you turn to me and groan, then you shall be saved, and you shall know where you have been: for you trusted in idols, your strength became vain; and you were unwilling to hear, but you said, 'We will flee upon horses'; therefore you shall flee; and, 'We will ride upon swift steeds'; therefore those who pursue you shall be swift. A thousand will flee at the threat of one, and at the threat of five, many will flee. The Holy One, whom I had kept silent about his name, is the Lord God, who speaks to you and through me and through Jeremiah (Jeremiah XII): If you repent and either abandon vices or the error of evil counsel, and remain in Judah, fearing not the attack of the Babylonians, but my commandments, you will be saved. Rest and hope in the Lord, and take hold of the strength of faith in my promises. You, who have despised the commandments of life and have said in despair, it will not be as you speak; instead, we will flee to the Egyptian horses and go swiftly to them in haste. […]

So useful are trials for Christians that through them, our spirit becomes a sacrifice to God. For it is written in the psalm: "The sacrifice acceptable to God is a broken spirit; a broken and contrite heart, O God, you will not despise." Enlightened by …

Would you know the power of repentance? Would you understand this strong weapon of salvation and the might of confession? By confession Hezekiah routed 185,000 of the enemy. That was important, but it was little compared to what shall be told. The same king's repentance won the repeal of the sentence God had passed on him. For when he was sick, Isaiah said to him, "Give charge concerning your house, for you shall die, and not live." What expectation was left? What hope of recovery was there when the prophet said, "For you shall die"? But Hezekiah did not cease from penitence, for he remembered what was written: "In the hour that you turn and lament, you shall be saved." He turned his face to the wall, and from his bed of pain his mind soared up to heaven—for no wall is so thick as to stifle reverent prayer—"Lord," he said, "remember me." "For it is sufficient for my healing if you remember me. You are not subject to circumstances but are yourself the legislator of life. For not on birth and conjunction of stars, as some vainly say, does our life depend. No, you are the arbiter, according to your will, of life and the duration of life." He whom the prophet's sentence had forbidden to hope was granted fifteen further years of life, the sun turning back its course in witness thereof. Now while the sun retraced its course for Hezekiah, for Christ it was eclipsed, the distinction marking the difference between the two, I mean Hezekiah and Jesus. Now if even Hezekiah could revoke God's decree, shall not Jesus grant the remission of sins? Turn and lament, shut your door and beg for pardon, that God may remove from you the scorching flames. For confession has the power to quench even fire; it can tame even lions.

It is never too late to repent. You may have gone down from Jerusalem and may have been wounded on the way; yet the Samaritan will set you upon his beast and will bring you to the inn and will take care of you. Even if you are lying in your grave, the Lord will raise you though your flesh may stink. At least imitate those blind men for whose sake the Savior left his home and heritage and came to Jericho. They were sitting in darkness and in the shadow of death when the light shone upon them.
