Most of the world religions feature common themes within. A deity is worshiped, a problem with the world is observed, and a solution proposed. While these features are present in biblical Christianity, the differences between it and other religions are vast. Biblical Christianity has its founding, salvation work, and conversion in the Creator God.
What distinguishes Christianity from other faiths is that it is not man discovering and developing, but God disclosing and dictating. God is the founder.
Whatever the specifics, salvation in the world’s religions can generally be categorized as accomplished through man’s exertions. Christianity is not fundamentally a religion of external improvement, but internal re-birth.
In this way, biblical Christianity is the photo negative of the world’s religions. Salvation is God’s doing, not man’s. This is a major difference between Christianity and all other world religions.
