God created us for a purpose. The purpose of God is our primary reason for being alive. If we live our lives without fulfilling the purpose of God that will mean failure. To fulfill our life, we must endeavor to fulfill the purpose of God for our life. We are not just living aimlessly. No, we are not existing because we wanted to exist. We are existing because God determined that we should exist. Our existence is determined by God Himself. Therefore whatever we engage ourselves in doing must be such that brings the purpose of God in our life to reality.
What is this purpose of God? The purpose of God is that we should do the good works which God has prepared for us before He created us. God planned our creation. He made us by Himself. He made us for a purpose. The purpose for which we were created is what the Bible tells us. The Bible records that God created us for good works. We are to be doers of good works. We may choose to do what pleases us with our life but we must understand that God wants us to be doing good to our fellow humans. We are not existing to increase the problems in the world, we are are existing to do good works.
