38 Then certain of the scribes and Pharisees answered, “Teacher, we want to see a sign from you.” 39 But he answered them, “An evil and adulterous generation seeks after a sign, but no sign will be given it but the sign of Jonah the prophet. 40 For as Jonah was three days and three nights in the belly of the whale, so will the Son of Man be three days and three nights in the heart of the earth. 41 The men of Nineveh will stand up in the judgment with this generation, and will condemn it, for they repented at the preaching of Jonah; and behold, someone greater than Jonah is here. 42 The queen of the south will rise up in the judgment with this generation, and will condemn it, for she came from the ends of the earth to hear the wisdom of Solomon; and behold, someone greater than Solomon is here.
43 But the unclean spirit, when he is gone out of the man, passes through waterless places, seeking rest, and doesn’t find it. 44 Then he says, ‘I will return into my house from which I came out,’ and when he has come back, he finds it empty, swept, and put in order. 45 Then he goes, and takes with himself seven other spirits more evil than he is, and they enter in and dwell there. The last state of that man becomes worse than the first. Even so will it be also to this evil generation.”
46 While he was yet speaking to the multitudes, behold, his mother and his brothers stood outside, seeking to speak to him. 47 One said to him, “Behold, your mother and your brothers stand outside, seeking to speak to you.” 48 But he answered him who spoke to him, “Who is my mother? Who are my brothers?” 49 He stretched out his hand towards his disciples, and said, “Behold, my mother and my brothers! 50 For whoever does the will of my Father who is in heaven, he is my brother, and sister, and mother.”

Commentary on Matthew 12:38-45
(Read Matthew 12:38-45)
Though Christ is always ready to hear and answer holy desires and prayers, yet those who ask amiss, ask and have not. Signs were granted to those who desired them to confirm their faith, as Abraham and Gideon; but denied to those who demanded them to excuse their unbelief. The resurrection of Christ from the dead by his own power, called here the sign of the prophet Jonah, was the great proof of Christ's being the Messiah. As Jonah was three days and three nights in the whale, and then came out again alive, thus Christ would be so long in the grave, and then rise again. The Ninevites would shame the Jews for not repenting; the queen of Sheba, for not believing in Christ. And we have no such cares to hinder us, we come not to Christ upon such uncertainties. This parable represents the case of the Jewish church and nation. It is also applicable to all those who hear the word of God, and are in part reformed, but not truly converted. The unclean spirit leaves for a time, but when he returns, he finds Christ is not there to shut him out; the heart is swept by outward reformation, but garnished by preparation to comply with evil suggestions, and the man becomes a more decided enemy of the truth. Every heart is the residence of unclean spirits, except those which are temples of the Holy Ghost, by faith in Christ.
Commentary on Matthew 12:46-50
(Read Matthew 12:46-50)
Christ's preaching was plain, easy, and familiar, and suited to his hearers. His mother and brethren stood without, desiring to speak with him, when they should have been standing within, desiring to hear him. Frequently, those who are nearest to the means of knowledge and grace are most negligent. We are apt to neglect that which we think we may have any day, forgetting that to-morrow is not ours. We often meet with hinderances in our work from friends about us, and are taken off by care for the things of this life, from the concerns of our souls. Christ was so intent on his work, that no natural or other duty took him from it. Not that, under pretence of religion, we may be disrespectful to parents, or unkind to relations; but the lesser duty must stand by, while the greater is done. Let us cease from men, and cleave to Christ; let us look upon every Christian, in whatever condition of life, as the brother, sister, or mother of the Lord of glory; let us love, respect, and be kind to them, for his sake, and after his example.
