Man is by nature sinful, and needs to be cleansed spiritually.
We are born into sin. Because God loves and values you so much, He made a way for you to be saved. He sent His Son, Jesus Christ to die so that mankind could be redeemed from sin. Salvation does not come by joining a church, following a certain religion, doing good deeds, or living a good moral life. The Bible says there is only one way to receive salvation.
