The Nature of Sin

What Scripture means by sin, why no sin is small, and why it is more than a mistake.

Why It Matters

Man's Greatest Problem

Ask people what is wrong with the world and you will hear many answers: poverty, ignorance, injustice, bad government. Scripture gives a deeper one. The problem is not only around us but inside us. Sin is man's greatest problem, and until we understand it, nothing else in the Gospel makes sense.

The angel told Joseph to name Mary's Son JESUS: for he shall save his people from their sins (Matthew 1:21). Jesus said He came to call sinners to repentance (Mark 2:17). Good news is good only against bad news. If sin is a small thing, the cross is an overreaction. If sin is what Scripture says it is, the cross is our only hope. We must see the depth of our sinfulness to see the value and beauty of Jesus.

We believe every person is born with a sinful nature inherited from Adam, and that because of that nature every person sins by choice. No one can reform himself or stop sinning by his own power. This topic asks what sin is. The Fall and Its Effects asks where it came from and what it has done to us.

DefinitionSin

Any failure to conform to God's law, or any transgression of it, in thought, word, or deed. Sin is lawlessness (1 John 3:4), a falling short of God's glory (Romans 3:23), rebellion against God (Isaiah 1:2), and unbelief (Romans 14:23). It is both something we do and something we are.

The key question

Sin is not first a matter of how we compare with other people. It is a matter of where we stand with God. Against thee, thee only, have I sinned, David prayed (Psalm 51:4).
