How do we know that God preserves our soul?

The preservation of our soul is a key tenet of sovereign grace theology. In Psalm 121, it states, 'The Lord shall preserve thy soul,' indicating God's active role in keeping us secure. This is echoed in 1 Peter 1:5, which highlights that we are kept by the power of God through faith for salvation. Furthermore, Jesus Himself assures us in John 10:28 that once we are His sheep, we will never perish, providing a firm foundation for the belief that our souls are eternally preserved by His sovereign grace.
