'Apply' in the Bible

You hypocrites (play-actors, pretenders)! You know how to analyze and intelligently interpret the appearance of the earth and sky [to forecast the weather], but why do you not intelligently interpret this present time?

and by conscience I mean for the sake of the other man’s, not yours. For why is my freedom [of choice] judged by another’s conscience [another’s ethics—another’s sense of right and wrong]?

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.
