Matthew 21:28 “What do you think? A man had two sons. And he went to the first and said, ‘Son, go and work in the vineyard today.’ And he answered, ‘I will not,’ but afterward he changed his mind and went. And he went to the other son and said the same. And he answered, ‘I go, sir,’ but did not go. Which of the two did the will of his father?” They said, “The first.” Jesus said to them, “Truly, I say to you, the tax collectors and the prostitutes go into the kingdom of God before you. For John came to you in the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes believed him. And even when you saw it, you did not afterward change your minds and believe him.
Isaiah 35:8 And a highway shall be there, and it shall be called the Way of Holiness; the unclean shall not pass over it. It shall belong to those who walk on the way; even if they are fools, they shall not go astray.
Jeremiah 6:16 Thus says the LORD: “Stand by the roads, and look, and ask for the ancient paths, where the good way is; and walk in it, and find rest for your souls. But they said, ‘We will not walk in it.’
2 Peter 2:21 For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them.
Psalms 81:11-12 “But my people did not listen to my voice; Israel would not submit to me. So I gave them over to their stubborn hearts, to follow their own counsels.
Zechariah 7:11-12 But they refused to pay attention and turned a stubborn shoulder and stopped their ears that they might not hear. They made their hearts diamond-hard lest they should hear the law and the words that the LORD of hosts had sent by his Spirit through the former prophets. Therefore great anger came from the LORD of hosts.
Hebrews 3:12 Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God.
This is a parable; the design of which is to show the hypocrisy and deceit of the Scribes and Pharisees, in pretending to works of righteousness, and not doing them; and to reprove them for their disbelief and rejection of John’s ministry; and to make it appear, that the worst of sinners in the Jewish nation were preferable to them. There are many churchgoers that imitate these sons. They admit that the Word of God is true. They intend to get serious about it someday. They talk about doing the Father’s work. They keep up the external appearance of religion, but their heart is not right with God. They think that words and promises are enough. “The second son said, ‘I go, sir,’ but he went not; and these people do not go. They talk of repenting, but they do not repent. They speak of believing, but they never believe. They think of submitting to God, but they have not submitted themselves to him yet. They say it is time they broke up the fallow ground, and sought the Lord, but they do not seek him. It all ends in a mere promise.” (Spurgeon)
The point of this parable is clear. What matters is living for God, not saying the right words. The religious leaders were good at talking righteous talk, but their stubbornly unrepentant hearts showed that repentant sinners would enter the kingdom before them. When you meet people with hearts like flint, you know they did not become that way overnight. There was a gradual, certain progression to their present place of hardness. It begins with simply refusing to heed God, then a self-justifying shrugging of their shoulders, then stopping their ears. It all ends with hearts as hard as flint. In their hardened state, they just didn’t want to hear God’s word. When we lose our hunger for God’s word it is sobering evidence of the progression of rejection and hardness of heart. The progression from a soft heart (able to hear the call of God to repentance) to a hardened heart (unable to recognize or hear the call of God to repentance) is one that can happen very fast (immediate and lasting rejection) or it can happen over a long period of time (a continued recognition of the call to repentance and rejecting it over and over again until it can’t be heard). At the end of the day, both have rejected the loving, merciful, and graceful call of God. Though some may have the appearance of doing the right things and saying the right things, their hearts are as hard as stone to the call from God to repentance.
