1. Faith in what is invisible (1-3)
Faith is confident hope in what we cannot currently see. We cannot see that the universe was created from nothing by God's command, but that is the basis of spiritual knowledge. Faith is the core quality of all the great men and women of the Bible.
2. Pleasing God (4-6)
What distinguished those who pleased God with their service (Abel) from those who did not (Cain)? Faith alone is what made Abel's offering acceptable. Those who live by faith are declared righteous by God. Enoch's example shows that faith is a life-long walk that sets us apart from the world and finally leads to victory over death. We need to believe in the great reward of living by faith.
