Note 5 at Php 2:14: When we let God work in our lives, to will and to do His good pleasure, we become free from murmurings and disputings.

The word "murmurings" is the Greek word "GONGYSMOS," and it was translated in the New Testament twice as "murmuring" (Joh 7:12 and Ac 6:1), once as "murmurings" (this verse), and once as "grudging" (1Pe 4:9). Its Greek meaning carries the idea of "a murmuring, muttering" (Vine's Expository Dictionary) and a displeasure and complaining that is more private in nature than public; i.e., a "secret displeasure, not openly avowed" (Thayer's Greek-English Lexicon).

The word "disputings" was translated from the Greek word "DIALOGISMOS." This word was also translated "doubtful" in Ro 14:1 and "doubting" in 1Ti 2:8. It carries the idea of arguing and quarreling that does not bring about the righteous life that God desires (Jas 1:20).
