What does the Bible say about the inability to come to Christ?

In John 6:65, Jesus emphasizes that the ability to approach Him is contingent upon divine intervention. He asserts that unless it is granted by the Father, no man can approach Him. This underscores the total depravity of humanity and the necessity for sovereign grace in salvation. Individuals, by their natural state, lack the ability to seek God—you may see this in passages like Ephesians 2:1-3, which highlight that we are dead in our sins until God intervenes and quickens our hearts. This truth highlights the importance of acknowledging God's sovereignty in the process of salvation.
