25 Withhold thy foot from being unshod, and thy throat from thirst: but thou saidst, There is no hope: no; for I have loved strangers, and after them will I go.
Nothing makes God as angry as when people from despair of better things cling to those that are worse. Indeed, this despair in itself is a sign of unbelief. One who despairs of salvation can have no expectation of a judgment to come. For if he dreaded such, he would by doing works prepare to meet his Judge. Let us hear what God says through Jeremiah: “Withhold your foot from a rough way and your throat from thirst,” and again, “shall they fall, and not arise? Shall he turn away, and not return?”
(Verse 25.) Keep your foot from nakedness, and your throat from thirst. And you said, I have despaired, I will not do it. I have loved strangers, and will follow after them. LXX: Turn your foot away from the rough path, and your throat from thirst. She said, I will act boldly because I have loved strangers, and I will follow after them. They who will celebrate the Passover are commanded to have shoes on their feet (Exodus 12). And the Apostle (Ephesians 6) preaches to have feet shod ready for the Gospel: lest while they walk through the solitude of this world, they be exposed to venomous creatures, which are to be trodden upon and crushed by the Gospel foot. We prevent our throat from being thirsty, when we fulfill the commandments of the Savior saying: Whoever is thirsty, let him come to me and drink (John 7:37). By this despair of evil, she denied that she would do what the Lord commanded, and she explained the reason, saying: I have loved strangers, and I will follow them, thinking that by this impudent confession she could avoid sins. Furthermore, next to the road of sinners there is a rough path, which is turned into a smooth path by the Lord. Let anyone who follows heretics be noted for the praise of this verse; for he said, I have despaired, whether I act boldly in evil, and I will be strengthened in my error. However, it is necessary for someone who follows a different doctrine from the Church to love those who are different and to follow their footsteps, whether they are demons or the leaders of heretics who are alienated from God.
