Philippians 1:27 (KJV) Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;
The best way to live our lives to please God is to live our lives according to the gospel of Jesus Christ. The way of the gospel is the way we should live our lives, people who want to please God. So, if as a teenager, someone wants to live his life and please God, he should follow the teachings of Jesus Christ. The teachings of Jesus Christ is the only way we can live our lives and it will please God.
