Why Commandments at All?
God gave the commandments to a people He had just set free, to show them how to live in love and stay free. Catholics number them following St Augustine, while some other Christians group the same verses differently.

What this lesson teaches
- God gave the commandments after freeing His people, so they are a way of life for the free, not a burden for slaves.
- The commandments spell out what love of God and love of neighbor require in daily life.
- Catholics and Lutherans follow St Augustine's numbering; Orthodox and many Protestants group the same verses differently.
- Real freedom grows as we choose the good, because sin always ends up enslaving us.

A sample question from this lesson
What does God say to Israel just before giving the commandments?
- That they must earn His favor by obeying
- That He brought them out of slavery in Egypt
- That the law will be replaced one day
- That only the priests must keep every rule
Show the answer
That He brought them out of slavery in Egypt. The commandments begin with God's rescue: "I am the Lord thy God, who brought thee out of the land of Egypt." The law follows freedom, it does not buy it.
The lesson in the app has three questions, each with an explanation.
