I know you didn't ask me but asked Free but if you don't mind I'd like to offer my understanding.
But Freeindeed, would Christ grant salvation to someone like I described?
First of all, I don't think anyone here would be so bold as to say for sure they know exactly what Jesus will or won't do. I can say this though with confidence and that is the fact that you are asking questions demonstrates to me that the Holy Spirit is calling you, tugging at you, wooing you to learn more about the Messiah and His love for you!
Serious question, as a Jew, I haven't read the new testament, so I don't exactly know what you are saying.
Start at the book of John, then the other Gospels. John is a great book to learn about the wonderful humanity that God, in the form of Christ Jesus, displayed and showed to all the world through the life of Christ.
If the only thing that matters is Christ's salvation, then what would happen to me? I follow the rules in the old testament that Adonai gave to Moses, except for the outdated ones (I own no slaves nor have ever bought a wife). Am I missing something?
Is not about following the rules to be saved but trusting in Christ who gives us the spirit to follow the law for the reasons of love, not to be saved.
When we follow Christ following the "rules" becomes part of our nature.
If I may I'd like to recommend a Messianic Rabbi that has a firm grasp on the law and following Christ. He is quite good and I think you'll find his teaching quite helpful...
Here a little, there a little
Let thou without sin cast the first stone, none are without sin, but is there such a thing as morals without G-d?
Morals without God? Well, in a way I suppose. God has written His law on your heart and when you do good towards others it is evidence of that law written on your heart, even if you don't know or rejects He who wrote those laws on your heart. (Romans 2:14-16)
It's what allows most of us, whether we are Christian or not, to know that beating up a defenseless old lady and stealing her purse is wrong. What's harder though is to look in a mirror and realize we are no better ourselves than the thief that accosted the old lady!
Another great book that I think you'd enjoy is quite short but quite powerful and will introduce you the the real Jesus Christ.
Steps to Christ
May the Lord continue to call and may you continue to listen to His voice!
John 10:27 My sheep hear my voice, and I know them, and they follow me:
Rev 3:20 Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with him, and he with me.
