So if YHWH can forget his promises to Israel, how then are you assured that he will remember his promises to you?
Forget the Torah.
There's your problem right there.
Christ was the fulfillment of the old covenant;
I think you had better ponder what 'fulfillment' means.
[...] and the old covenant (old testament) was superceded by the new covenant (new testament.)
Each and every covenant dovetails into the next - why wouldn't the Messianic covenant do the same? And in fact, it does.
Even Moses, in the Torah, warned Israel to listen to Christ:
Even as Yeshua warned you to listen to Moses.

I am quite certain that if I don’t break any covenants between me and God, he will look favorably on me.
>>>Even as Yeshua warned you to listen to Moses.<<<
I did listen to Moses. He told me to listen to Christ, and I do.
