According to Einstein's General Theory of Relativity, the answer is no.
That's the equation: t = t0/(1-v^2/c^2)^(1/2). Which means if God speeds up, he is likely to stay forever. So practically if he can move at 99.999...% of the light speed C, he can stay always and everything else will get older and older very fast.
But, that's another problem. At the light speed, there is only one time, no past, no future, only today and now. God at light speed can't go to past to change things, he can't go to the future to make things, he should stay at the current time, and always there. At speed of light C always, all past and all future is just the current time, at least that is what the Einstein's formula is.
So can an all powerful God with infinite energy, go past?
The answer is no.
According to Einsteins formula E=Eo/(1-v^2/c^2)^(1/2), to stop the time, even for the smallest particle, even for the smallest Planck time (tp = 5.39 × 10^-44 s), infinite energy, which means infinite power is needed.
So the all powerful God should consume infinite energy, just to stop the time for a finite particle, for a finite period of time. And that is just a full stop, not going back.
