Q. 3: From where do you know your misery?
A: From the law of God.
Q. 4: What does the law of God require of us?
A: Christ teaches us this in summary, in Matthew 22:37-40: “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength. This is the first and great commandment. And the second is like unto it, You shall love your neighbor as yourself. On these two commandments depend all the law and the prophets.
Q. 5: Can you keep all these perfectly?
A: No, for I am prone by nature to hate God and my neighbor.

Lord’s Day 2A

Parents’ Preparation: Read Heidelberg Catechism Q&A 3-5

Song: “On the Good and Faithful” (Psalm 4)

Readings: Romans 2:14-15; 3:20; 7:7; Heidelberg Catechism Q&A 3


1. 1. Read Romans 3:20 and 7:7. How do you know that stealing your classmates’ ball pen is a sin? How about jaywalking? How do you know if a thought, word or action is a sin?

2. Read Romans 2:14-15. Do you feel guilty if you did something that you know is wrong, even if you’re not aware of any law against it?

3. If someone doesn’t have a Bible, how does he know right and wrong? Does anyone have an excuse for not knowing the law?

Dear heavenly Father, thank you that you have revealed to us in the Bible whether we have done right or wrong. Thank you also that you have written your law in the hearts of all people, so they may know right from wrong even if they don’t have Bible. In Jesus’ name we pray. Amen.
