'Reason' in the Bible

And for the same reason I sent you a letter so that I might be certain of your desire to do my orders in all things.

For this reason, because we have been made servants of this new order, through the mercy given to us, we are strong:

For this reason we make it our purpose, in the body or away from it, to be well-pleasing to him.

For this reason, from this time forward we have knowledge of no man after the flesh: even if we have had knowledge of Christ after the flesh, we have no longer any such knowledge.

For the sorrow which God gives is the cause of salvation through a change of heart, in which there is no reason for grief: but the sorrow of the world is a cause of death.
