God's Word is the bottom line.
You may not lie to accomplish what you consider to be a godly aim. You may not bite back at someone because you think he has done something bad to you. You may not enhance a story to persuade the listener to side with you.
Your behavior is not to be determined by circumstances, but by God's Word.
He never fails.
He never changes.
He never compromises.
He never leaves us.
He is The Truth.
He is The Life.
He is The Way.
He is The Door.
He is the Bright and Morning Star.
He is the Rose of Sharon.
He is the Lion of Judah.
And more.
He is always right. His Word is always true.
