Heidelberg Catachism

3. Q. From where do you know your sins and misery?

    A. From the law of God.

4. Q. What does God’s law require of us?

A. Christ teaches us this in a summary in Matthew:

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 neighbor as yourself.

All the Law and the Prophets hang on these

two commandments.
