Jesus of Nazareth was the Son of God! His death was an atoning sacrifice He made to God, to pay for the sins of all who place their trust in Him.  God is morally perfect, and He requires moral perfection of us all. But no one is perfect -- far from it! Until we become His children, our sins and pride build a wall between us and God.

But Jesus was perfect. He out of love chose to substitute Himself on the cross for sinners. When God raised Christ, on what came to be known as Easter Sunday morning, it showed two facts: God affirmed Jesus' own sinlessness, and God accepted Jesus' death on behalf of others. 

You cannot be saved by keeping the Ten Commandments, going to church, taking the communion, being christened/baptized, going forward to the altar, or following Jesus' moral teachings. You can be justified of your sins by trusting in Jesus, and His death and resurrection for you!. Morality expresses the renewed person you become.

We don't get into God's kingdom by faith, then stay in by works. It's by faith in Christ through and through!
