Will Jesus return on a white horse?

[Undeceived]

Ever try asking the average Christian or Catholic what the Ten Commandments are? They don't even know all Ten Commandments.

You make a very general statement that is not altogether accurate or fair. In my experience, people know what's right and what's wrong. That is all the Ten Commandments are. They aren't some magical code that, if people follow them, they will be upright citizens. Jesus upheld the "spirit of the law," telling people to love God and love their neighbor. He hit the root of human behavior. If you don't love, you won't do good for long. Goodness has to come from the inside out. That's why "any average Christian" will be able to tell you about a NT verse on love--because love is more important than knowing rules. Rules are mere knowledge. Love is the driving force for good. And the ultimate model for love is Jesus' sacrifice--a righteous, perfect God dying for his destructive, disobedient creation.

It was not Jesus who taught that you did not have to try and keep the Ten Commandments. That was all Paul!

Neither said you did not have to try. Paul writes in Romans 3:28-31:
"For we maintain that a person is justified by faith apart from the works of the law. Or is God the God of Jews only? Is he not the God of Gentiles too? Yes, of Gentiles too, since there is only one God, who will justify the circumcised by faith and the uncircumcised through that same faith. Do we, then, nullify the law by this faith? Not at all! Rather, we uphold the law."
Romans 6:1-4:
"What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We are those who have died to sin; how can we live in it any longer? Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life."
Trying is a wonderful pursuit. That is why God makes us a "new creation" (2 Cor. 5:17) through his death, so we have the inner desire to do good deeds.
