1 Timothy 4:1
Now the Holy Spirit specifically says that in later times [Note: "Later times" in the New Testament usually refers to the period following the first coming of Christ and the establishment of the church], some people will fall away from the faith [i.e., the true teaching of Christianity]. They will pay attention to deceitful spirits [i.e., lying people] and the teaching of evil spirits.
1 Timothy 4:8
For physical training is useful to some extent [or, "for a short time"], but living godly is useful in every way, for it promises benefits [not only] for the present life, but [also] for the life to come.
1 Peter 3:12
For the Lord's eyes see what the righteous person does and He hears their [earnest] prayers, but the Lord looks with disapproval on the person who does wrong."
