'Truth' in the Bible

But we have rejected shameful hidden deeds, not behaving with deceptiveness or distorting the word of God, but by open proclamation of the truth we commend ourselves to everyone's conscience before God.

As the truth of Christ is in me, this boasting of mine will not be stopped in the regions of Achaia.

For even if I wish to boast, I will not be a fool, for I would be telling the truth, but I refrain from this so that no one may regard me beyond what he sees in me or what he hears from me,

For we cannot do anything against the truth, but only for the sake of the truth.
