Why is divine grace essential for approaching God?

Scripture makes it clear that approaching God is not within the capability of the unregenerate individual. The natural state of man is described as having their understanding darkened and being alienated from the life of God (Ephesians 4:18). Therefore, divine grace is necessary to overcome this blindness and spiritual deadness. John 6:44 states that no one can come to Christ unless drawn by the Father, indicating that it is the Holy Spirit who awakens the heart to want to seek God. This divine initiative is a testament to God's sovereignty in salvation, showcasing that it is not by human effort but grace that people can come to Him.
