> You're grasping at straws to argue what you have decided against before the conversation began.
I liked your comment and only had nitpicks with a few items that I mentioned.
> You'll have to be more specific. We can't have much of a meaningful conversation if we're just dancing with generalities. To what alleged broken promises are you referring?
Christian supersessionism in every form I've heard it necessitates the conversion of the Jewish people to Christianity in order to remain in God's (new) covenant. God said in the Hebrew Bible that his covenant with Abraham's descendants would last forever, and that his commandments would not change. Yes I know Paul redefines "Abraham's seed" to refer to all people who are "in Christ" but it's a stretch for me. If God's commandments and promises don't change, it's impossible for a new commandment (believe in Jesus) to be added as a requirement for the Jewish people.
> Correct. If there is an equally powerful malevolent being, then God cannot be omnipotent because He would not, then, be necessarily able to do all things that are proper objects of His power.
Yeah I have no problem with this.
> As far as all our experience has shown, time on Earth is linear in one direction only. We would have to move forward to move backward in time, a contradiction. The ability to change the past would render all things unstable in consequence. Your point that God should be able to change the past is far from supported, let alone proven.
There's no fixed direction of causality at the fundamental level. The appearance that time flows from past to future comes from the fact that entropy was low in the early universe and is comparatively higher now. On a local level, all laws of physics are time-reversible and events in the future can affect the state of a system in the past. https://en.wikipedia.org/wiki/Retrocausality
