Acts 4:12 Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.
Just as the Apostles continued to show people how important it was to know what Jesus had done for us all; how He had given His own life in our stead so we could be freed from our debt for the sins we do.
No matter how many sacrifices we offer up to God, they are not going to be any better than the perfect sacrifice Jesus was for us.
This is why we owe everything to Christ and this is why we need to know the truth about Jesus.
