Is it a sin to be left-handed?

from the old testament

• God created all men and women in His image (Genesis 1:26–27), giving them equal value. This means He created our physical bodies (Genesis 2:7). Before the fall, God called everything He made—which would include our physical bodies—-as “very good” (Genesis 1:31). Nothing about our bodies is inherently sinful.
• Scripture never condemns left-handedness nor the use of the left hand. Indeed, David once praised God, saying, “You formed my inward parts; you knitted me together in my mother’s womb. I praise you, for I am fearfully and wonderfully made” (Psalm 139:13–14a). God personally creates both left- and right-handed people.
• In fact, some Bible passages praise left-handed individuals: “Then the people of Israel cried out to the LORD, and the LORD raised up for them a deliverer, Ehud, the son of Gera, the Benjaminite, a left-handed man” (Judges 3:15). The author comments on Ehud's left-handedness because it was key to how Ehud could surprise and kill the enemy king of Moab by using his left hand (Judges 3:20–21).
• The tribe of Benjamin was known for skillfully using their left hands in battle (Judges 20:16) and even for being ambidextrous, able to use either hand with equal skill (1 Chronicles 12:2). Scripture mentions this feature to highlight and praise their unique skill.
• Sin arises from our evil hearts (Jeremiah 17:9), not from physical features like being left-handed.
• Samuel initially assumed that Jesse’s most handsome son was the one God would make king (1 Samuel 16:6). However, God said, “Do not look on his appearance or on the height of his stature, because I have rejected him. For the LORD sees not as man sees: man looks on the outward appearance, but the LORD looks on the heart” (1 Samuel 16:7).

from the new testament

• Jesus grounded sin internally, not in physical features. He siad, "What comes out of a person is what defiles him. For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. All these evil things come from within, and they defile a person" (Mark 7:20-23).
• When Jesus' disciples assumed that a man had been born blind because he or his parents had committed a sin, Jesus corrected that by saying, "It was not that this man sinned, or his parents, but that the works of God might be displayed in him" (John 9:3). In that case, the physical feature of the man (his blindness) was to display God's glory when Jesus healed him, not to display sin. Physical features are not in themselves sin (though they may be a result of the fall).
• James writes, "So whoever knows the right thing to do and fails to do it, for him it is sin" (James 4:17). John defines sin as "lawlessness" (1 John 3:4). None of these associates a physical feature, such as left-handedness, with sin.

implications for today

Every culture has superstitions. One superstition that has been passed down through some cultures is associating left-handedness with sin. But the reality is that being left-handed is just one of many expressions of the genetic diversity God built into humanity.

Whether left-handed or right-handed, the truth is we were all born internally sinful. We have evil hearts (Jeremiah 17:9), evil desires (James 1:14–15). Jesus explained that lust and hatred (internal desires) are the same thing as committing adultery and murder (Matthew 5:28; Matthew 5:21–22). Whether we have the opportunity to fulfill our desire, we would do so if we could.

God alone sees our hearts (1 Samuel 16:7), knows our thoughts (Psalm 139:2), and will hold us responsible (Ecclesiastes 12:14). But the good news is that He sent His Son, Jesus, to pay for even the internal sin we keep hidden from others. By being perfect, Jesus was the only one who never sinned. Since the penalty for sin is death (Romans 6:23a), He did not need to do so. However, He willingly did so that all who trust in Him will be saved (Romans 10:9–10). Rather than focusing on appearance, consider your own heart. Are you repentant and trusting in Christ for your salvation? If not, confess your sin today.
