Why is it important for Christians to understand the new birth?

The new birth is crucial for Christians as it highlights the necessity of divine intervention in the salvation process. John 3:3 underscores that without being born again, one cannot see the kingdom of God. This understanding fosters humility and acknowledges that salvation is not a human achievement but a gift from God. Additionally, understanding the nature of the new birth encourages believers to rely on God’s grace rather than their own works, affirming that spiritual life comes from God's sovereign will and power, as articulated in passages like Titus 3:5.
