True Worship and the Blood that Speaks a Better Word Genesis 4:1-12 with Hebrews 12:22-24 God’s Gospel promise provokes true worship by faith; but for the unbelieving – idolatry, jealousy, and murder. 1. Cain and Abel model carnal versus true worship. (Genesis 4:1-7) 2. Cain murders Abel – persecuting God’s redeemed worshiper – and his blood cries out for justice. (Genesis 4:8-12) 3. Christ’s blood cries out for mercy for us – and He mediates our true Gospel worship. (Hebrews 12:22-24)
