Hebrews 11:1-4 New Revised Standard Version (NRSV)
The Meaning of Faith
11 Now faith is the assurance of things hoped for, the conviction of things not seen. 2 Indeed, by faith[a] our ancestors received approval. 3 By faith we understand that the worlds were prepared by the word of God, so that what is seen was made from things that are not visible.[b]
The Examples of Abel, Enoch, and Noah
4 By faith Abel offered to God a more acceptable[c] sacrifice than Cain’s. Through this he received approval as righteous, God himself giving approval to his gifts; he died, but through his faith[d] he still speaks.
