The word mark appears in many places of the Bible besides the book of Revelation. A more in depth study of the word mark opens up deeper understanding.
Set a Mark - Genesis 4:15
Concordance # G226; the Lord set a Mark upon Cain; sign, signal, distinguishing mark, a remembrance, miracle. From # G225, evidence, standard, consent, agree
The Lord Set a Mark upon Cain. Cain had killed his brother. Cain was envious because Abel worshipped God in God's preferred manner and Cain felt that his manner was the only and best way. So he killed his brother. God marked Cain to prevent anyone from killing him for his sin. The sin Adam & Eve had done by eating the poison fruit (false worship) Cain continued on with expanding sin. God did not kill Adam & Eve but expelled them from the Garden. When Lucifer rebelled in Heaven and took 1/3 of the wicked Angels with him, God did not kill him. Time had to elapse to show the true nature of the Great Controversy between Christ and Satan.
