1 John 3:12. Cain, the son of Adam and the bother of Abel, made his own choice to murder his brother. 1 John 3:12 says, "...Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous." Cain only murdered Abel because his brother was righteousness. The way of Cain is to hate righteousness.

BIBLE SCRIPTURE: 1 John 3:12, "Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous."

Most of us are familiar with the story of Cain and Abel. Abel brought a worthy offering to God, an offering of blood, and God was well pleased. Cain made a personal choice to bring God an unworthy offering. This was an offering of the ground, the cursed ground. Soon after that in the field, Cain rose up against Abel his brother and killed him (Genesis 4:3-8, " An in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen? If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him. And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.").

BIBLE SCRIPTURE: Genesis 4:8, "And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him."

The devil did not make Cain a murderer. God did not condemn Cain to be a murderer. God even counseled Cain after he had made an unworthy offering. God desired Cain to do well (Genesis 4:7, "If thou doest well, shalt thou not be accepted?"). Soon after God counseled him Cain murdered his brother Abel. Cain made a personal choice to continue in his disobedience resulting in the murder of his brother Abel.

BIBLE SCRPTURE: Genesis 4:7, "If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him."

Just like Cain we all can make a personal choice to hate righteousness. When we come in contact with something that we know is God's Truth, we can complain about it, be resentful, be envious, deny it, lie about it, and even hate it with a murderous spirit. Because of our sin nature that we inherited from Cain's father Adam, we can all make a personal choice to be disobedient to God. We all can choose to hate God and His Truth. Thanks to Jesus' sacrifice for our sin nature, we do have another choice. We have the choice to love God and love our brother.
