James says many things about how to live for God. The first would be Trials and temptation. James says "Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance." Meaning that there in fact IS light at the end of the tunnel
The second point James makes is LISTENING AND DOING Meaning listen to the word of God is one thing but acting on it is another. James simply dares us to do it.
For the fifth point James said TAMING THE TOUNG Speech can either be a blessing and a curse it just depends on what you chose to say. James tells us to,instead of using your gift of speech to hurt others to worship God and give him thanks for all you have.
For the last point James says PATIENCE IN SUFFERING Suffering is not a lifetime thing. "You too, be patient and stand firm, because the Lord's coming is near"
All of these tie Into tough love because whilst applying these things not everyone is going to agree with what your doing so while you still love and care for them you might loose a few friends.
