How do we know that the power of God is not limited by human unbelief?

The narrative in Mark 6 demonstrates that while God's power is limitless, its manifestation can be hindered by human unbelief. Jesus, despite having the ability to perform mighty works, could not do so in Nazareth due to the people's lack of faith. This does not suggest a limitation to God's power but rather signifies a divine judgment upon those who reject Him. Thus, the presence of unbelief often results in the withdrawal of God's blessings, reminding believers of the seriousness of their response to the gospel and the spiritual consequences that can follow from it.
