Q. 73 Which is the eighth commandment? A. The eighth commandment is, Thou shalt not steal. Psalm 104 shows that God is the Creator of all things, who provides for His creatures by: Supplying water to the beasts and to the earth itself (v. 10-13). Providing all sorts of things for man (v. 14-15). Not just for our necessities, but also for our enjoyment (John 

-8, 1 Tim 4:3-4). Providing homes for the various animals He has made (v 16-18). Ordaining means by which each creature obtains its food (v. 19-23). For man, it is by labour and industry. Truly the earth is full of God's possessions (Psalm 104:24)!

The idea of imparting a body of truth (rudiments of the faith) is found repeatedly in scripture under many different terms and descriptions. We are not given a complete catechism or confession in the Bible. That is because we are to write our own according to the needs of the day. They must refute new heresies as they arise. Our Lord has called us to catechise in His church… to teach disciples the basics of the faith. Make the most of this instruction: memorise your Catechism, listen to the messages, and pray for the Spirit to work.
