'May' in the Bible

He must hold firmly to the trustworthy word [of God] as it was taught to him, so that he will be able both to give accurate instruction in sound [reliable, error-free] doctrine and to refute those who contradict [it by explaining their error].

This description is true. So rebuke them sharply so that they will be sound in the faith and free from doctrinal error,

not paying attention to Jewish myths and the commandments and rules of men who turn their backs on the truth.

to be sensible, pure, makers of a home [where God is honored], good-natured, being subject to their own husbands, so that the word of God will not be dishonored.

sound and beyond reproach in instruction, so that the opponent [of the faith] will be shamed, having nothing bad to say about us.

not stealing [things, regardless of value], but proving themselves trustworthy, so that in every respect they will adorn and do credit to the teaching of God our Savior.

This is a faithful and trustworthy saying; and concerning these things I want you to speak with great confidence, so that those who have believed God [that is, those who have trusted in, relied on, and accepted Christ Jesus as Savior,] will be careful to participate in doing good and honorable things. These things are excellent [in themselves] and profitable for the people.

Our people must learn to do good deeds to meet necessary demands [whatever the occasion may require], so that they will not be unproductive.
