First, its important to understand why its important to be a Christian. We see in scripture (Romans 3:23) that all men, including you and me, are sinners, and fall short of the expectation of God. No one is perfect in the world, and we all make mistakes. However, God is perfect, and so we cannot get to Heaven with our sinful nature, with all the wrongs we have done. We are condenmed to hell in the state that we are in. But there is hope! God is willing to forgive you of your sin, through Jesus Christ, the sacrifice sent for you and me. The love of God is so great that God sent his own son Jesus to die and take our sins from us, who died and rose from the grave. God is willing to forgive us of our sin so we can be with him for eternity, and all you have to do is to believe in Jesus.
