The new birth is essential because it is the work of the Holy Spirit that enables a person to have faith and eternal life.
The doctrine of the new birth is paramount in Reformed theology, reflecting the necessity of being 'born again' as articulated by Jesus in John 3. It is through this spiritual rebirth that individuals are able to perceive and grasp the truths of the Gospel. Ephesians 2:1 describes that we were dead in trespasses and sins, reinforcing the doctrine that human beings cannot initiate salvation; rather, it is a divine act of God through the Holy Spirit. The role of the Spirit is crucial in giving life to those who are spiritually dead, effectively enabling them to respond in faith to the Gospel message. Without this new birth, as emphasized by Jesus, there is no entry into the Kingdom of God.
