In the gospels, Jesus teaches a parable about a sower and seeds. Some of the seeds show signs of growth and life, yet all of them, save one seed, do not survive. The planted seed of the gospel can have a temporary, life-giving effect on some who have not truly repented, but those who endure and bear fruit are those who prove to be Christ’s disciples. Likewise, the writer of Hebrews tells his audience it is impossible to renew to repentance those who merely tasted the heavenly gift of Christ’s church, but who ultimately fall away and despise the Lord. He wants the church to endure in hope until the end, being diligent in their faith, not lazy. Finally, the writer argues that God wants to show his unchangeable purpose through his promises to his people.
