Why is regeneration important for salvation?

Regeneration is a vital theology in Reformed thought, signifying the spiritual rebirth that is necessary for salvation. 1 John 5:1 indicates, 'Whosoever believeth that Jesus is the Christ is born of God.' This means one must be born anew, or regenerated, before they can truly believe and come to Christ. Regeneration changes a person's heart and mind, making them receptive to the gospel and the spiritual realities of Christ's atoning work. Without this divine intervention, no one would willingly turn to God or embrace Christ as Lord and Savior.
