'Conscience' in the Bible

For our reason for boasting is this: the testimony of our conscience that we conducted ourselves in the world, and especially toward you, in holiness and purity of motive from God, not in merely human wisdom, but by the grace of God.

but we have renounced shameful hidden things, not behaving with craftiness or adulterating the word of God, but with the open proclamation of the truth commending ourselves to every person's conscience before God.
