Q.From where do you know your sins and misery?
A. From the law of God.
Q.What does God’s law require of us?
A. Christ teaches us this in a summary in Matthew 22:
Love the Lord your God with all your heart and with all your soul and with all your mind. This is the first and greatest commandment. And the second is like it: Love your neighbour as yourself. All the Law and the Prophets hang on these two commandments.
Q.Can you keep all this perfectly?
A. No, I am inclined by nature to hate God and my neighbour.
