Hebrews 11:4

"By faith Abel offered to God a better sacrifice than Cain, through which he obtained the testimony that he was righteous, God testifying about his gifts, and through faith, though he is dead, he still speaks".

"Their son Abel understood the blood and Hebrews 11:4 says that by faith Abel offered to God a more excellent sacrifice than Cain through which he obtained witness that he was righteous. God testifying to His gifts and through it "He being dead speaks today". That's an amazing Scripture! That through blood Abel FELT righteous but Cain brought just fruit from the land and God was not pleased with his sacrifice so at the beginning of humanity, we see that Abel though he is dead, still speaks today. That without blood there can be no approach to God, no favour of God, you cannot know God experientially, you cannot walk with God - there is no grace, no blessing, no power in your life without the blood - the manifest Presence of God is absent".
