Everyone has fallen short of God's expectations and need salvation to be made right. Jesus is the only way to salvation, but the journey will look different for everyone. Jesus came into this world to be the sacrificial lamb in obedience to God's Word. While he was here he made the old testament make sense and gave life to the standard of living.
Jesus had people that he had to forgive. Before he became the sacrificial lamb all of his closest friends betrayed or abandoned him. Each one of those men needed to be forgiven and they were, except for Judas. Judas killed himself before he could face Jesus. I guess he didn't realize that he would still have to face Jesus on judgment day.
Jesus' apostles could not move forward and become the men of purpose that they did without Jesus first forgiving them. The Bible doesn't mention most of the forgiveness stories, but it does tell us how Jesus forgave Peter and then how they were anointed to serve God for the rest of their lives. The same goes for you. You cannot fulfill your purpose unless you are forgiven by Jesus. He has to forgive you for you to be able to approach the Lords Table.
Jesus forgives because he loves you. Forgiveness is love in action. It is the hardest part of love. Jesus shows you how to forgive and restore the relationship. Even if a relationship is not restored, you can love people enough to forgive. When you forgive people, you reveal how much you love Jesus. Forgiveness is taking care of people who do not take care of you. The purpose of forgiveness is to release you from the burden, stay close to Jesus, and be able to keep growing in your faith. If the other person benefits, then it is a path for you to use to introduce them to Jesus or meet him in a new way.
