Joshua,
Jesus says in Matthew 5:22, which says that "I tell you that anyone who is angry with his brother will be siubject to judgment. Again, anyone who says to his brother, 'Raca,' is answerable to the Sanhedrin. But anyone who says, 'You fool!' will be in danger of the fire of hell (NIV)." The thing is, the anger we experience is out of selfishness. We get angry because someone cut us off on the highway, so now we can't go as fast as we wish we could. We get angry because someone yelled at us, even though Jesus says that we should bless those who curse us. Jesus had the true, perfect anger. It is only recorded once where Jesus got angry, when He turned over the money tables in the temple. He did this for the right reason, sinful people were making God's house as a market.
Jesus looks past our good works. In Matthew 19, Jesus says, "If you want to enter life, obey the commandments (17b, NIV)." Then Jesus continues when the rich young man says that he kept all the commandments "If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me (21, NIV)." He looks to the heart. Yes, the man kept all the commandments, except He was greedy about the money God provided him (we don't have money, God owns everything).
Jesus does not care about the Law, all He cares about is Love and Grace. "But the greatest of these is love" 1 Corinthians 13:14b states in the NIV. Love is all that matters. If a person is a Christian, they will love. It will be easy for a Christian to love since they are in God, and God is love (1 John 4:8), and God will be in them.
I hope you can understand this, I'm really tired right now, and I still have to type a Bible paper tonight!
Have a blessed evening
