Read Isaiah 1:11-20 and compare it with John 4:23-24

“Come now, and let us reason together,” Says the Lord, “Though your sins are like scarlet, they shall be as white as snow; Though they are red like crimson, they shall be as wool. If you are willing and obedient, you shall eat the good of the land; But if you refuse and rebel, you shall be devoured by the sword”; For the mouth of the Lord has spoken. Isaiah 1:18-20
