What God will do for you as a believer is through the everlasting covenant. And I will make an everlasting covenant with them, that I will not turn away from doing them good; but I will put my fear in their hearts so that they will not depart from Me (Jeremiah 32:40). Through the everlasting covenant, what God will do is revealed. What God will do for you is through Christ, our great Shepherd (Hebrews 13:20-21).
And I will make an everlasting covenant with them. This is a remarkable contrast with the old covenant law. It was a temporary covenant (Hebrews 8:13). The people of God broke it. It was conditional, based upon the peoples obedience. God's will for you as a believer in Christ is in the everlasting covenant. What God will do in you is based upon the obedience of Christ Jesus.
I will not turn away from doing them good. Under the conditional promises of the old covenant law, God had to turn away from doing good to His people, because of their sins and transgressions. Their disobedience brought the curse of the law. What God will do for you is through the everlasting covenant in Christ, who died to take away the curse of sin for you. God will not turn away from doing you good (Romans 8:28).
I will put My fear in their hearts so that they will not depart from Me. Under the old covenant law, God's people turned away from Him, even to the point of serving false gods in idolatry. What God will do for you is revealed through the everlasting covenant. He has changed your heart (Romans 2:28-29). God has put His fear in your heart, that you will not depart from Him.
