Ten Commandments Part 2 - Love, New Birth, Faith

It is very good for theological truths to be stated plainly, as is done here in verse 1.

Faith in Jesus as the Christ comes from the new birth that God gives.
Love for God extends also to the children of God.

But because the devil always is trying to deceive us, and because there are all kinds of phoney religions and false teachers in the world around us, we need even more help in knowing what is true biblical Christianity and what is not.

So, along with the propositional statements of the truth, our Lord Jesus shows us the practical use of God's commandments in identifying the true and the false in religion.
