Why is Christianity unique?
Christianity offers a Saviour
Another of the unique features of Christianity is that it offers you a Saviour. All other religions say that you must save yourself; by good deeds etc. Trying to save yourself cannot work. We have sinned against God and those sins must be punished. It is too late for us to try and go back and change that. Doing good works does not erase the sins that we have already committed. The only way is to have a Saviour. If you want a Saviour there is only one and His name is Jesus. This Saviour has paid the price for our sin. We do not need to try and cover it up or solve the situation ourselves. Jesus has paid it all, we just need to accept his gift. We need to admit that we are sinners, that we have fallen short of God's standards. We need to ask Jesus to wipe our sins away and ask Him to forgive us. He has promised that if we do that He will save us from our sin, He will help us to live that life that pleases Him and will one day take us to be with Him forever.
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.John 3:16
