'Reason' in the Bible

The person who loves his brother abides in the light, and there is no reason for him to stumble.

See what kind of love the Father has given us: We are called God's children and that is what we are! For this reason the world does not recognize us, because it did not recognize him, either.

The person who practices sin belongs to the evil one, because the Devil has been sinning from the beginning. The reason that the Son of God was revealed was to destroy what the Devil has been doing.
