(Hebrews 11:4 NIV) "By faith Abel offered God a better sacrifice than Cain did. By faith he was commended as a righteous man, when God spoke well of his offerings. And by faith he still speaks, even though he is dead."
(1 John 3:12 NIV) "Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother's were righteous."
(Jude 1:11 NIV) "Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam's error; they have been destroyed in Korah's rebellion."
Cain and Abel both brought offerings to God. Both believed in God, but Abel’s sacrifice was pleasing and acceptable, while Cain’s offering was rejected. One can argue about the nature of their offerings -- why one was accepted and the other one was not. But one thing that is not debatable is that there is still a “way of Cain”, and there is still such a thing as unacceptable worship offerings. It has little to do with style, day, place, or amount. It has more to do with the attitude, character, and heart of the one bringing the offering. Abel’s offering was about love, relationship, and genuine sacrifice. Cain’s worship was about duty and religion. These two brothers represent a fork in the spiritual road of humanity. These two roads separate and stretch into eternity, but they arrive at very different places. Which road are you on? Whose way will you take? -- Friar Tuck’s Word of the Day
