This page is for someone who is not totally convinced that Christ is the Savior.
In the Bible, an unbeliever is someone who lacks faith in Jesus Christ as the Son of God and Savior, rejecting the gospel message, and instead places trust in themselves, worldly things, or false philosophies. This isn’t just about not believing God exists (even demons do), but a failure to entrust their spiritual well-being to Christ, often described as being spiritually dead or blind to God’s truth, and characterized by a life apart from God’s ways.
The most accurate term depends on the person’s specific beliefs or lack thereof, but non-Christian, atheist, agnostic, or their specific faith (e.g., Jewish, Muslim) are common ways to describe someone who doesn’t accept Christ as the savior
