Job's sin and Adam's

When Adam sinned, he furthered his sin by a religious sin: he covered himself (Genesis 3.7) with fig leaves.

When he sinned, rather than come to God for forgiveness, he sought his own "religious" solution: a covering of his own making.

Our sin-bent response to sin is to avoid God, to stay away from church, to avoid prayer, when what we need is to confess, forsake, and cleave to God.

In seeking to understand what has happened to him, Job explicitly denies this religious sin. He doesn't claim to be sinless, but he didn't follow Adam's sin: "If [and the if is an if of denial] I covered my transgressions as Adam." (Job 31.33)
