Would you be able to give up everything you own and follow Jesus?

If life was a test to see if we were worthy enough to get to heaven, would anybody get to heaven? Given inclusion of that text in Matthew 19:21-24, that is a valid question, because Jesus implied that the lure and temptations of materialism (great wealth) would prevent entry. When the disciples exclaimed "Who then can be saved?" Jesus replied "With men this is impossible but with God all things are possible". Never mind what any movie says about that! Stick to Jesus' own words!

Soteriology is the Christian doctrine of salvation, so the need is to see what the Christian doctrine of salvation states. The trouble is, there are two basic views on how people can be saved (the understanding with all mainstream Christian denominations being that those saved will get to be with Christ in heaven.) There is what is called Monergism, and then there is Synergism, so that needs to be spelled out first.

Monergism (one working) holds that God saves sinners without their assistance.

Synergism (working together) teaches that salvation depends on our co-operation.

Protestantism largely says that humans are born in sin, and are incapable of any movement toward God apart from his grace. The Reformed traditions teach that God not only gives sufficient grace for us to cooperate toward our own (spiritual) rebirth but actually grants the new birth and faith prior to any human decision or activity. Rebirth, therefore, is the one working of God - monogeristic.

"With respect to the doctrine of salvation (soteriology), it is this single point that most decisively distinguishes the churches of the Reformation from all other traditions... However, monergism teaches that God's grace accomplishes everything, even granting us repentance and faith." Pilgrim Theology, pp 250-1, Michael Horton, Zondervan 2011

The same writer in the book just quoted explains what binds, and prevents, people from proving themselves worthy of heaven:

"Our will can choose only that in which our nature delights. If our nature is in bondage to unbelief, then our will is not free with respect to God. By nature, we 'by [our] unrighteousness suppress the truth' (Ro 1:18). 'Are we Jews any better off? No, not at all; for we have already charged that all, both Jews and Greeks, are under sin, as it is written, 'None is righteous, no, not one; no one understands; no one seeks for God' (Ro 3:9-11). The fallen mind is darkened to the gospel apart from the Spirit's gift of faith (1 Co 2:14)... We are saved for works, not by works (v.10)." Ibid. p. 249

Nor will it do to say that, once God has saved us, as a totally unmerited act of grace, we can then start piling up a heap of good works that will show we deserve heaven. No, for that would deny that God's grace is unmerited, that we "were dead in the trespasses and sins in which [we] once walked... But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ (Eph 2:1-2, 4-5).

"Even so then at this present time also there is a remnant according to the election of grace. And if by grace, then it is no more of works; otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work." Romans 10:5-6 A.V.

That last quote from the Bible sums it up. And it helps explain why Jesus set the bar for heaven so impossibly high for humans. Only God can do the impossible and save sinners. Once he has saved us, with heaven as our final destination, we see how we are saved for good works, not by good works. Nothing we can do can ever make us 'worthy' for heaven; only what Christ has freely done for us meets the requirements of perfection needed to get into heaven. That is the monergistic answer to the question.
