Righteousness from God comes through faith in Jesus Christ to all who believe

“But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify.  
This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference,  for all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus.  
God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished— he did it to demonstrate his justice at the present time, so as to be just and the one who justifies those who have faith in Jesus.” 
                                                                Romans 3:21-26
The basic belief of Christianity is that” all have sinned and fall short of the glory of God.”
Christians also believe that we cannot work our way to heaven. Paul writing to the Ephesians saying,
“For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God—  not by works, so that no one can boast.”
                                                                          Ephesians 2:8,9.
That we are justified before God by the redemption that came by Christ Jesus. God presenting Jesus as a sacrifice of atonement through faith in his blood.
Once again this is something that no other faith offers.
In Christianity it is God that reaches down to mankind. Offering us a free, if you will, ticket to heaven.
We do not have to sacrifice animals, or take pilgrimages. We do not need to worry about whether or not our good deeds will out weigh our bad deeds on judgement day because Jesus died for us.
Paul writing to the Romans stating,
“But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” 
Romans 5:8.
All anyone has to do to get to heaven is believe on the Lord Jesus Christ and you shall be saved.
Think about it.
