Although there are similarities with other religions here and there, Christianity does have a few points that distinguishes it from other religions.
Christianity teaches that Jesus is the only way to get into heaven (John 14:6).
Being right with God is a gift of grace, not something that we can accomplish through our own works (Ephesians 2:8-10). By the book, Christianity is not a religion of works.
Christianity teaches that we are to love everyone, including our enemies (Matthew 5:43-44) and the poor (1 John 3:17). Followers of the faith have not always lived this out, but it is a clear teaching of Jesus.
Christians are supposed to continue living on the life of Jesus in the here and now (Ephesians 2:18). They are to love the way Jesus loved, do the things Jesus would do, and continue on His mission to liberate mankind from the sins that shackle them.
