Because of sin and death, they are enslaved to fear. Fear drives the sin nature.
[Jhn 8:34 NASB] 34 Jesus answered them, "Truly, truly, I say to you, everyone who commits sin is the slave of sin.
[Heb 2:14-16 NASB] 14 Therefore, since the children share in flesh and blood, He Himself likewise also partook of the same, that through death He might render powerless him who had the power of death, that is, the devil, 15 and might free those who through fear of death were subject to slavery all their lives. 16 For assuredly He does not give help to angels, but He gives help to the descendant of Abraham.
[Jhn 3:19 NASB] 19 "This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil.
[1Jo 4:18 NASB] 18 There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love.
Adam was created perfect without a sin nature. He had a divine nature, yet was capable of sinning. We, though in our fallen state have a sinful nature, are capable of good because we know good and evil and have God's good law on our hearts in spite of our eternal destination and dominant nature.
[Deu 30:1, 6, 11-15, 19 NASB] 1 "So it shall be when all of these things have come upon you, the blessing and the curse which I have set before you, and you call [them] to mind in all nations where the LORD your God has banished you, ... 6 "Moreover the LORD your God will circumcise your heart and the heart of your descendants, to love the LORD your God with all your heart and with all your soul, so that you may live. ... 11 "For this commandment which I command you today is not too difficult for you, nor is it out of reach. 12 "It is not in heaven, that you should say, 'Who will go up to heaven for us to get it for us and make us hear it, that we may observe it?' 13 "Nor is it beyond the sea, that you should say, 'Who will cross the sea for us to get it for us and make us hear it, that we may observe it?' 14 "But the word is very near you, in your mouth and in your heart, that you may observe it. 15 "See, I have set before you today life and prosperity, and death and adversity; ... 19 "I call heaven and earth to witness against you today, that I have set before you life and death, the blessing and the curse. So choose life in order that you may live, you and your descendants,
The OP makes a claim anti-thetical to Deuteronomy 30. He says it is too difficult for you to make the choice for life and blessing... and that you must go & have the help of heaven to hear it.
What does Paul say about Deuteronomy 30?
[Rom 10:5-10 NASB] 5 For Moses writes that the man who practices the righteousness which is based on law shall live by that righteousness. 6 But the righteousness based on faith speaks as follows: "DO NOT SAY IN YOUR HEART, 'WHO WILL ASCEND INTO HEAVEN?' (that is, to bring Christ down), 7 or 'WHO WILL DESCEND INTO THE ABYSS?' (that is, to bring Christ up from the dead)." 8 But what does it say? "THE WORD IS NEAR YOU, IN YOUR MOUTH AND IN YOUR HEART"--that is, the word of faith which we are preaching, 9 that if you confess with your mouth Jesus [as] Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
This is diametrically opposed to the OP. He would have us believe that the word is not near to us or in our heart, but rather that we must first regenerate (or ascend into heaven to bring God as the Holy Spirit down to make us hear) to choose life.
