The Christian convert as God’s new creation (2 Corinthians 5:17) does not contain the power to persevere. Rather, the new creation contains the link to the one who daily provides the power to persevere, and that link is assured. Paul says, because it is sustained decisively by God, not man. This is why Paul insists, “God is faithful; he will surely do it” (1 Thessalonians 5:24; cf. 1 Corinthians 1:9).
