'Deciding' in the Bible

But concerning the Gentiles who have believed, we have written a letter [after] deciding they should avoid food sacrificed to idols and blood and [what has been] strangled and sexual immorality."

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]?
