'Deciding' in the Bible

But concerning those of the nations who have believed, we have written, deciding that they should observe no such thing, only to keep themselves both from things offered to idols, and from blood, and from things strangled, and from fornication.

I now pass to another subject. Receive as a friend a man whose faith is weak, but not for the purpose of deciding mere matters of opinion.

Therefore, [when I] was wanting [to do] this, perhaps then was I making use of vacillation? Or was I deciding what I was deciding according to the flesh, in order that with me my "yes" may be "yes" and my "no" [may be] "no" [at the same time]?

Let the peace of Christ [the inner calm of one who walks daily with Him] be the controlling factor in your hearts [deciding and settling questions that arise]. To this peace indeed you were called as members in one body [of believers]. And be thankful [to God always].
