What does the Bible say about the need for a spiritual miracle?

In Ephesians 2:1, we see that humanity, being dead in trespasses and sins, requires a miraculous act by God to bring about new life. This regeneration is essential for understanding spiritual truths and accepting the gospel of salvation. Without this divine intervention, people remain spiritually blind and incapable of grasping the depths of God’s mercy. The need for a miraculous transformation emphasizes the sovereignty of God in salvation, showing that it is through His power alone that hearts are changed and opened to the truth of Jesus Christ, the friend of sinners.
