It is evident that the Bible does not record all that was Communicated to man; however, the careful student sees that sacrificial Worship was a Divine revelation. The statements that Cain BROUGHT and Abel BROUGHT their respective sacrifices, may indicate that there was a Specific time and place where offerings were presented to God (Genesis 4:1-4 ). In addition to this, we learn that Abel offered his sacrifice by faith, (Hebrews 11:4 ), and that faith comes by hearing the word of God (Romans 10:17 ); that Cain sinned (Genesis 4:7; is the transgression of the law (1 John 3:4 ).
