How do we know grace is essential for understanding the Bible?

Understanding the Bible is intricately linked to God’s grace. Without grace, our hearts are indifferent or resistant to the gospel, akin to the hard and thorny soils in the parable of the sower. Scripture indicates that it is God who must reveal the truths of His word to us, as seen in Luke 8:10 where Jesus states that to some, the mysteries of the kingdom are revealed, while to others, they remain parables. This reinforces that understanding comes not from human effort but from divine grace that opens our eyes and hearts to the truth of God's word.
