'May' in the Bible

But you must let endurance have its full effect, so that you may be mature and complete, lacking nothing.

But someone may say, "You have faith, and I have actions." Show me your faith without any actions, and I will show you my faith by my actions.

Above all, brothers, do not swear oaths by heaven, by earth, or by any other object. Instead, let your "Yes" mean yes and your "No" mean no! Otherwise, you may fall under condemnation.

Therefore, make it your habit to confess your sins to one another and to pray for one another, so that you may be healed. The prayer of a righteous person is powerful and effective.

you may be sure that whoever brings a sinner back from his wrong path will save his soul from death and cover a multitude of sins.
