How do we know that God's mercy is not deserved?

The message from Ezekiel illustrates that there is nothing in us that could ever merit God's mercy. The infant in the field was described as polluted and deserved of nothing but condemnation. Similarly, all of humanity is in a state of sin with no inherent worthiness of grace. The Bible consistently emphasizes that God's mercy is determined by His will alone, as shown in Romans 9:15, where He states, 'I will have mercy on whom I will have mercy.' This teaches us that salvation is not contingent upon our actions but entirely upon God's gracious choice.
