This brings intensity or special importance to make a point clear, such as “Be careful to obey [God’s directions]…
do not turn from it…be careful to do everything…” (Josh 1:7,8, 23:6). Sometimes even within a single verse the
Bible reinforces a truth, eg “It is for freedom that Christ has set us free” (Gal 5:1).
Peter used repetition to highlight the importance, “So I will always remind you of these things, even though you know them and are firmly established in the truth you now have. I think it is right to fresh your memory…always be able to remember these things” (2 Pet 1:12-15).
While there is the need to emphasize various truths, there is also the requirement to accurately present both sides by bringing the
clarifying Scriptures into focus. An example is, while God will forgive confessed sin, you are
required to "leave your life of sin”, not continuing in it, so you can experience more of His grace (Jn 8:11; Rom 6:13; 1 Jn 1:9).
