Sin and Forgiveness in Christianity: Original Sin, Repentance, and How to Forgive Others
Sin and forgiveness are central themes in Christian theology, shaping human nature, salvation, and relationships. The Bible teaches that sin separates humanity from God, but through repentance and Christ’s sacrifice, forgiveness is made available to all. This article explores original sin, the importance of repentance, and the biblical approach to forgiving others.
1️⃣ What is Original Sin?
Definition of Original Sin
- Original Sin refers to the fallen state of humanity inherited from Adam and Eve’s disobedience in the Garden of Eden.
- It is the tendency toward sin that all humans inherit from birth.
- Because of this, every person is in need of salvation through Jesus Christ.
Biblical Basis for Original Sin
📖 Genesis 3:6-7 – The Fall of Man
“When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it. Then the eyes of both of them were opened, and they realized they were naked.”
📖 Romans 5:12 – Sin Entered the World
“Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned.”
