Mankind's Problem:
Sin
MAN CHOSE TO SIN AGAINST GOD RATHER THAN SERVE HIM.  THE
BIBLE SAYS...

"For all have sinned and come short of the glory of God." Romans 3:23

What does it mean to sin against God?
Sin is breaking God's law (1 John 3:4)

We sin by doing what God has commanded us not to do or by not doing what
God told us to do.
