The new birth is essential because it transforms a person into a child of God, enabling them to understand spiritual truths.
The necessity of the new birth is emphasized in John 3, where Jesus declares to Nicodemus that 'except a man be born again, he cannot see the kingdom of God.' This new birth is not a decision made by man but a divine act of God. As described in John 1:12-13, believers are 'born, not of blood, nor of the will of the flesh, nor of the will of man, but of God,' establishing that true conversion is a supernatural work. The new birth grants a person a new nature, enabling them to comprehend and respond to spiritual truths that were previously hidden from them. Without this transformational work of the Holy Spirit, a person cannot enter or even perceive the kingdom of God.
