'Reason' 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.

just as you have also understood us in part, that we are your reason for boasting, just as you [are] also ours in the day of our Lord Jesus.

Because for this [reason] also I wrote, in order that I could know your proven character, whether you are obedient in everything.

For indeed we who are in this tent groan, being burdened {for this reason, that} we do not want to be unclothed, but to be clothed, in order that what is mortal may be swallowed up by life.
