“Do not think that I came to bring peace on earth. I did not come to bring peace, but a sword. I came to divide a man against his father, and a daughter against her mother, and a bride against her mother-in-law. [Ones] hostile [to] the man [shall be] those of his [own] house. The [one] loving father or mother more than Me is not worthy of Me. And the [one] loving son or daughter more than Me is not worthy of Me. And who does not take up his cross and follow after Me is not worthy of Me. The [one] finding his life shall lose it. And the [one] losing his life on account of Me shall find it. The [one] receiving you receives Me, and the [one] receiving Me receives Him who sent Me” (Matthew 10:34-40).
My biological brother is ignorant of the righteousness of God revealed in the gospel (cf. Romans 10:1-4). I pray for his salvation as Paul did for the salvation of ignorant Israel. My father rejects my imitation of Paul, giving this as his reason for doing so: “Because he’s my son.” In other words, though my brother according to flesh (i.e., biological) is ignorant of God’s righteousness, my father will contradict Paul because “he’s my son.” This is just one salient, somber, and sober example of “loving” son more than Jesus Christ.
Thomas Watson writes (this is not a promotion of Watson or Jerome as true Christians):
“It was a saying of Jerome, ‘If my parents should persuade me to deny Christ; … if my wife should go to charm me with her embraces, I would forsake all and flee to Christ.’ If our dearest friends alive would lie in our way to heaven, we must either leap over them or tread upon them.” (Thomas Watson, Heaven Taken by Storm).
This enticing to go and “serve other gods” is a demonstration of hatred. Those whose eye DOES “have pity” or would “spare” or “hide,” and NOT kill, demonstrates more “love” to them than to Jehovah.
“If your brother, your mother’s son, or your son, or your daughter, or the wife of your bosom, or your friend who [is] as your own soul, shall entice you secretly, saying, Let us go and serve other gods, which you have not known, you and your fathers, of the gods of the people around you, [those] near you or far off from you, from one end of the earth even to the other end of the earth, you shall not consent to him, nor listen to him, nor shall your eye have pity on him, nor shall you spare nor hide him. But killing you shall kill him; your hand shall be first upon him to cause him to die, and the hand of all the people last. And you shall stone him with stones, and he shall die, for he has sought to thrust you out from Jehovah your God, who brought you out of the land of Egypt, out of the house of slaves. And all Israel shall hear and fear, and shall not again do any such wicked thing as this among you” (Deuteronomy 13:6-11).
