We can know God through human reason, but only in a very limited way. Yet if God exists and is personal, He may well want to speak to us. But how? Through nature, private revelation, prayer, organized religion? Genuine divine revelation should agree with what we have learnt about God through reason (lesson 3). God has revealed himself progressively, in words and deeds, to the people of Israel, leading up to the fullness of his revelation in Jesus the Messiah. Divine revelation is God's "map of life" for us.
