'Reason' in the Bible

Though I am not conscious of having been in any way unfaithful, yet I do not for that reason stand acquitted; but He whose scrutiny I must undergo is the Lord.

For this reason I have sent Timothy to you. Spiritually he is my dearly-loved and faithful child. He will remind you of my habits as a Christian teacher--the manner in which I teach everywhere in every Church.

For this reason I would have you understand that no one speaking under the influence of The Spirit of God ever says, "Jesus is accursed," and that no one is able to say, "Jesus is Lord," except under the influence of the Holy Spirit.
