Since the children have flesh and blood, He too shared in their humanity so that by His death He might break the power of him who holds the power of death—that is, the devil—and free those who all their lives were held in slavery by their fear of death.
But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror. For he looks at himself and goes away and at once forgets what he was like. But the one who looks into the perfect law, the law of liberty, and perseveres, being no hearer who forgets but a doer who acts, he will be blessed in his doing. James 1:22-25 ESV
“And if you faithfully obey the voice of the Lord your God, being careful to do all his commandments that I command you today, the Lord your God will set you high above all the nations of the earth. And all these blessings shall come upon you and overtake you, if you obey the voice of the Lord your God. Deuteronomy 28:1-2 ESV
This Book of the Law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.” Joshua 1:8-9 ESV
