Why did some people understand Jesus, and others didn't? The answer lies in who received the 'giving'.
Jesus’ response highlights a crucial point: the ability to understand the truths of God's kingdom is not a matter of intellectual superiority or merit, but a gift from God.
He states plainly, 'To you it has been given...' and 'but to them it has not been given.' This points to God's sovereign choice in revealing Himself. It wasn't that the disciples were inherently better or more deserving. Rather, God, in His wisdom and timing, chose to grant them understanding.
This doesn't mean God is unfair. It means His ways of revealing Himself are profound and not always aligned with human expectations. For those who received the gift, it was an act of grace, opening their eyes to see and ears to hear what others, for reasons known to God, did not perceive.
