Philippians 2:14-18 teaches us several truths that are vital to the Christian life. We are told to do all things without grumbling and disputing, while living a life that is blameless, innocent and without blemish. Doing so will produce a testimony that will be a light to the world. Paul emphasizes also to treasure the Word of God and share it with others. Ultimately doing all of these things is pleasing to God and will lead to gladness and rejoicing among believers.
