What does it mean to be a rebel sinner?

In the context of sovereign grace theology, a rebel sinner is characterized by their nature which leads them to reject God's sovereignty and grace. By default, every human is in opposition to God, viewing Him not as the sovereign Creator, but as a negotiable deity who must accommodate their preferences. The rebellion manifests through disobedience, which brings condemnation. However, through regeneration by the Holy Spirit, a person can be awakened to their sinful condition and drawn to acknowledge God's rightful authority, leading to repentance and faith.
