2 Kings 17:7 And this occurred because the people of Israel had sinned against the Lord their God, who had brought them up out of the land of Egypt from under the hand of Pharaoh king of Egypt, and had feared other gods and walked in the customs of the nations whom the Lord drove out before the people of Israel, and in the customs that the kings of Israel had practiced. And the people of Israel did secretly against the Lord their God things that were not right. They built for themselves high places in all their towns, from watchtower to fortified city. They set up for themselves pillars and Asherim on every high hill and under every green tree, and there they made offerings on all the high places, as the nations did whom the Lord carried away before them. And they did wicked things, provoking the Lord to anger, and they served idols, of which the Lord had said to them, “You shall not do this.” Yet the Lord warned Israel and Judah by every prophet and every seer, saying, “Turn from your evil ways and keep my commandments and my statutes, in accordance with all the Law that I commanded your fathers, and that I sent to you by my servants the prophets.”
But they would not listen, but were stubborn, as their fathers had been, who did not believe in the Lord their God. They despised his statutes and his covenant that he made with their fathers and the warnings that he gave them. They went after false idols and became false, and they followed the nations that were around them, concerning whom the Lord had commanded them that they should not do like them. And they abandoned all the commandments of the Lord their God
Deuteronomy 31:27 For I know how rebellious and stubborn you are. Behold, even today while I am yet alive with you, you have been rebellious against the LORD. How much more after my death!
2 Chronicles 36:13 He also rebelled against King Nebuchadnezzar, who had made him swear by God. He stiffened his neck and hardened his heart against turning to the LORD, the God of Israel.
Jeremiah 7:26 Yet they did not listen to me or incline their ear, but stiffened their neck. They did worse than their fathers.
Romans 2:4-5 Or do you presume on the riches of his kindness and forbearance and patience, not knowing that God’s kindness is meant to lead you to repentance? But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.
Hebrews 3:7-8 Therefore, as the Holy Spirit says, “Today, if you hear his voice, do not harden your hearts as in the rebellion, on the day of testing in the wilderness,
The starting point for avoiding a hardened heart is to recognize and submit to God’s authority through His inspired Word. To learn from God, we must submit to His inspired Word. As Paul says, these things “were written for our instruction”. We disobey or ignore them to our own peril (harden our heart). The starting point is that we hear His voice with a heart soft to the voice of God, the word of God. Thus, to avoid hardness of heart, we must submit to the authority of God’s Word and we must do business with God on the heart level. The only way that we can know God’s ways are as He has revealed them to us in the Scriptures. We can’t plead ignorance. We can’t protest, “But, God, I didn’t know”. When we have time but choose to neglect His word in our life, in our thoughts, in our heart, we have chosen to harden our heart and stiffen our neck against God. We follow the crowd and what is approved by society/culture rather than being led by the Holy Spirit through the Word of God. Your heart is either hardening against God because you are resisting His sovereign ways with you, or it is growing softer toward God because you are submitting to His Word and His ways. For God’s word to be active in your life, it must be actively desired in your heart and in your daily life. If it is only an occasional reading there is no softening of your heart to His word. Choose to be led, encouraged, strengthened, empowered, and softened by His word each day
