Hebrews 11:4-6

By faith Abel offered to God a more acceptable sacrifice than Cain, through which it was testified of him that he was righteous (upright, in right standing with God), and God testified by accepting his gifts. And though he died, yet through [this act of] faith he still speaks. [Gen 4:3-10] By faith [that pleased God] Enoch was caught up and taken to heaven so that he would not have a glimpse of death; AND HE WAS NOT FOUND BECAUSE GOD HAD TAKEN HIM; for even before he was taken [to heaven], he received the testimony [still on record] that he had walked with God and pleased Him. [Gen 5:21-24] But without faith it is impossible to [walk with God and] please Him, for whoever comes [near] to God must [necessarily] believe that God exists and that He rewards those who [earnestly and diligently] seek Him.
