Often, uncontrolled anger leads to more sins and serious consequences, as we see in the Bible story of Cain and Abel, where the first murder was recorded.
Today, the sin of murder still takes place among the people of the world. This act of evil tells us that whatever is happening in the world today has happened before. Moreover, it will continue to happen even to the end of time.
Therefore, our duty as Christians is to deliberately flee from every appearance of evil because it always results in severe repercussions. This article will reveal what led to the very first murder in the Bible and the powerful lessons it teaches.

The Story of Cain and Abel in the Bible
To understand the reason behind the first recorded killing in scripture, we must know the history of Cain and Abel.
Who are Cain and Abel in the Bible?

According to the biblical narrative of Genesis 4, in the Old Testament of the Bible, Cain and Abel are the children of Adam and Eve. Recall that Adam and Eve are the first humans God created, as we see in the account of creation (Genesis 2). The Lord placed the couple in the Garden of Eden and commanded them not to eat from the tree of the knowledge of good and evil.
One day, the serpent deceived Eve into eating the forbidden fruit, and she fell into the temptation. Eve offered the fruit to her husband, Adam, and he ate it too, thereby going against God’s command. As a result of Adam and Eve’s act of disobedience, God sent them out of the garden of Eden.

After leaving the garden, Adam and Eve started their lives afresh and had two sons. Their first son was named Cain, while his brother’s name is Abel. When the two boys grew up, Cain became a farmer, and his brother Abel became a shepherd.
Why Did Cain Murder Abel?

In time, Cain and Abel offered sacrifices to the Lord based on their respective occupations. While God accepted Abel’s sacrifices, probably because he gave the best, He rejected Cain’s offering. For this reason, Cain became so angry and jealous of his brother. Still, God reached out to Cain to warn him about the sin hovering around him.
The Lord also encouraged Cain to take control of his emotions, but he ignored God’s warning.
Afterwards, Cain asked Abel to follow him to the field, which he did without hesitation. Sadly, Cain attacked Abel while they were in the field and murdered him there, becoming the first murderer in the Bible.
Upon noticing Abel’s murder, the Lord inquired from Cain where his brother was. In response, Cain said to the Lord, “Am I my brother’s keeper?” Then, the Lord told Cain that the blood of Abel cries to Him from the ground. Considering the gravity of Cain’s sin, the Lord cursed him.
Despite Cain’s murderous act, the Lord put a mark on him so that no one would kill him. Thereafter, Cain got married and gave birth to a son whom he gave the name Enoch.

Lessons from the First Murder in the Bible
Every story in the Bible has one or more moral lessons to teach us as Christians today. Let’s discuss some of the key lessons from the story of Cain and Abel in the Bible.
1. Honor God With Your Resources
Abel was intentional about his sacrifices to the Lord. The Bible tells us that Abel brought the best portions of the firstborn lambs from his flock as a sacrifice to God. Similarly, we must be deliberate about everything we want to offer to God: our time, money, and other resources.
God is the giver of all things, and He deserves to receive the best from us. Apostle Paul encourages us as Christians not to give reluctantly or under compulsion because God loves a cheerful giver (2 Corinthians 9:7). If we honor God with our resources, He will reward us abundantly.
2. Keep Your Anger in Check
Cain’s anger resulted in jealousy, which eventually led to the murder of Abel. We all get furious, even as believers, which is okay. But when the anger becomes uncontrollable, there will be a problem.
God’s word, in Ephesians 4:26-27, warns us to keep our anger in check: “Be angry and do not sin; do not let the sun go down on your anger, and give no opportunity to the devil.” Those who can’t control their anger are dangerous, just as we see in the murder of Abel. For this reason, we must be careful about the way we live as children of God.
If you’re struggling with controlling your anger, ask the Holy Spirit for help. Similarly, consider taking anger management classes to stay calm when confronted with annoying situations.
3. Heed Divine Instructions
When God realized Cain was annoyed, He cautioned him to control the emotion. In other words, the Lord warned Cain not to allow his anger and jealousy to consume him because of their disastrous outcomes. Regardless, Cain refused to heed the divine warning and eventually carried out his evil plan. Eventually, Cain suffered the consequences of his disobedience and wickedness.
From the moment we give our lives to Jesus Christ, the Holy Spirit begins to call our attention to sinful actions to avoid. Moreover, the Bible reveals God’s commands to us that we need to obey. If we fail to follow God’s instructions, we will reap the reward of disobedience. We see several examples of those who rebelled against God in scripture and the result of their decisions.
Always remember the words of Hebrews 3:15 to remain obedient to God: “Today, if you hear His voice, do not harden your hearts as in the rebellion.”
4. Mercy Prevails Over Judgment

Though Cain committed a serious offense against God and man, he obtained mercy. In the biblical text of Genesis 4:10, the Lord revealed to Cain that Abel’s blood cries to him from the ground. This verse of the scripture suggests that God values the lives of humans so much, and He punishes murderers. But despite Cain’s wicked act, God showed him mercy. The Lord put a mark on him to prevent anyone who finds him from killing him.
From this part of Cain and Abel’s story, we learn that our God is merciful and compassionate. The Psalmist confirms that the Lord doesn’t accuse of sins, and He doesn’t remain angry forever (Psalm 103:9). So whenever you commit a sin, ask God for forgiveness immediately, and He will answer you. Know that God’s promises never fail, and His love endures forever.

Final Thoughts
Take some time to read the story of Cain and Abel again, and you’ll gain new insight about it. Understand that the spirit of anger is powerful and destructive, and it doesn’t operate alone. Cain became furious, jealous, and eventually murderous because of something he had no control over.
In most parts of the world today, the punishment for murder is life imprisonment or death. Therefore, be careful in your daily living as believers in Christ, and always ask the Holy Spirit to guide your decisions. Anger and jealousy are some of the appearances of evil that the Bible warns us about; flee from them!
