Heidelberg Catechism Question 13
Can we make this payment [for our sins] ourselves?
Matthew 6:12 – And forgive us our debts, as we also have forgiven our debtors.
Romans 2:4-5 – Or do you show contempt for the riches of his kindness, forbearance and patience, not realizing that God’s kindness is intended to lead you to repentance?
But because of your stubbornness and your unrepentant heart, you are storing up wrath against yourself for the day of God’s wrath, when his righteous judgment will be revealed.
