James
The book of James is called a general epistle, as it was written for circulation among many churches, and not to address a specific church issue. It was probably written by the James the son of Alpheus, who was one of the 12, and not the brother of John, who was killed by Herod.
The behavior of a child of God is to be upright before the world, which is something that can be seen in action, and not just heard. We must learn to put away anger, as it does not accomplish the righteousness of God. Our faith in Christ is demonstrated through our actions towards each other, without partiality or discrimination, showing the love of God to all. Our tongues are so small, yet cause so much trouble, and it is a rare thing for us to control it as God desires. Do not speak against one another, but humble yourself in the sight of the Lord - draw near to God, and He will draw near to you. Let the Lord have control of your plans. Pray for one another, because the effective and persistent prayer of a righteous person will accomplish much in His Name.
