In the Old Testament there are two sets of laws, the Mosaic law which is the basic set of moral laws then the Levitical or ceremonial laws which were the laws that men demanded. The scripture makes it clear that men cannot possibly keep the Levitical laws and struggle to consistently keep the moral law. God sent Jesus to fulfill the law not reinforce it and to pay the price of man’s failure to satisfy the law so that man may not be damned but by sincere faith in the Christ may find salvation from Gods wrath through the vicarious sacrifice of Christ. That is the entire bible in a nutshell.
The central tenet of Christianity is that Jesus is the way the truth and the life, there is no way to the Father except through him. So while your comment may be true of the false religions it is not true of Christianity.
