I believe it is a challenge for every single person in a cult/religion.
Low self-esteem comes from knowing we don't measure up AND believing the lie that we have to.
I believe this condition afflicts mostly honesthearted and sincere persons. Members of the Pharisaic ruling religious clergy class mostly respond with "militant ignorance" and "malignant self-righteousness" to convince or deceive themselves that they do measure up. Their supremacist externalism creates the camel gulping and gnat straining "whitewashed graves" Jesus spoke of.
Religion demands that we "measure up" to be right with God by following the "right" religious rules, religious moral code, religious doctrine and religious knowledge.
The gospel however offers IMPUTED righteousness (justification) as a free and unmerited gift (Rom 3:22-24).
Religion demands that we "clean up" to be holy for God by stopping sinning.
The gospel however offers IMPUTED holiness (sanctification) as a free and unmerited gift.
Religion makes liars of those embracing it: "We all sin, and those who say they do not sin do not have the truth and are making God out to be a liar (1Jo 1:8-10)" - from it-2 p. 96.
