'Helpful' in the Bible

Everything is permissible for me, but not all things are beneficial. Everything is permissible for me, but I will not be enslaved by anything [and brought under its power, allowing it to control me].

All things are lawful [that is, morally legitimate, permissible], but not all things are beneficial or advantageous. All things are lawful, but not all things are constructive [to character] and edifying [to spiritual life].

Be kind and helpful to one another, tender-hearted [compassionate, understanding], forgiving one another [readily and freely], just as God in Christ also forgave you.

Only Luke is with me. Get Mark and bring him with you, for he is very helpful to me for the ministry.

and let us consider [thoughtfully] how we may encourage one another to love and to do good deeds,
