Spiritual rebirth is essential for understanding and accepting God's truth, as our natural state is death in trespasses and sins.
The essential doctrine of spiritual rebirth stems from the realization that all of humanity, due to original sin, is in a state of spiritual deadness. Romans 8:5-7 explains that those who mind the things of the flesh are at enmity with God and cannot submit to His law. A natural man cannot comprehend spiritual truths; they perceive them as foolishness (1 Corinthians 2:14). Therefore, it is necessary for God to intervene and impart spiritual life, a new heart, and eyes to see the beauty of Christ. The rebirth, which is accomplished through the Holy Spirit, enables a person to recognize their utter depravity and the sufficiency of Christ's righteousness alone. Thus, without being born again, one cannot partake in the promises nor fully grasp the gospel of grace.
