"That the Jews assumed a right exclusively to the benefits of God will be a lasting witness against them and the same will it be against Christians"

This quote by William Blake speaks with the idea that both Jews and Christians have presumed a right to the advantages of God that is unique to them. Blake is suggesting that this presumption of exclusivity will be an enduring witness versus them, and that it will be remembered for a long time. This quote speaks to the idea that both Jews and Christians have a tendency to think that they are the only ones who are entitled to the benefits of God, which this mindset is wrong. Blake is recommending that this attitude of exclusivity will be remembered and will be an enduring witness against them. He is likewise recommending that this attitude of exclusivity is incorrect and need to be prevented. This quote speaks to the idea that both Jews and Christians must be open to the idea that everybody is entitled to the advantages of God, and that nobody should assume that they have a special right to them.
