Abel chose faith and obedience; Cain, unbelief and rebellion. Here the whole matter rested."
Patriarchs&Prophets E.G.W.
The first conflict recorded in Scripture between man was over worship. So too is the last conflict between man recorded in Scripture. In the end, the scene of innocent Abel falling before the murderous Cain will be repeated....over worship...and cause that as many as would not worship the image of the beast should be killed. Revelation 13:15
