How do we know that God grants understanding of the gospel?

The understanding of the gospel is a gift from God, rooted in His sovereign grace. In Matthew 13:10-11, Jesus explains to His disciples that it is given to them to understand the mysteries of the kingdom, implying that such comprehension is not universally bestowed but is selectively granted by divine will. This is a profound reflection of God's sovereignty in salvation; He opens the eyes and hearts of those He has chosen, enabling them to see their need for grace. The ability to truly grasp and respond to the gospel is intimately connected with this divine initiative, where the Holy Spirit prepares the heart to receive the truth of Christ's redemptive work.
