Read Hebrews 11 today.

This chapter is sometimes referred to as the roll call of the saints. I think of it as the ‘by faith’ chapter. As you read, consider how many times we find the phrase ‘by faith.’
Faith is essential if we are to please God. As you look back over your life, when have you had to exercise your faith or flex your faith muscles? How will you do so today?
Hebrews 11:1-2 NLT
Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see. [2] Through their faith, the people in days of old earned a good reputation.
Hebrews 11:6 NLT
And it is impossible to please God without faith. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him.
