How do we know that regeneration is necessary for salvation?
Answered in 3 sources
Regeneration, or being born again, is necessary for salvation as it is the work of God that transforms a person's heart and understanding.
Regeneration is essential because, without it, we remain in our natural state of spiritual death, just like the demoniac in Mark 5 who lived in a tomb. Jesus' interaction with this man illustrates the necessity of divine power to give life to the spiritually dead. In John 3:3, our Lord stated that one must be born again to see the kingdom of God. This rebirth is unattainable by human effort and is solely attributed to God's sovereign grace. Our acknowledgment of this gives glory to God for the work He alone can accomplish in transforming hearts.
