If we must pay a day worker before the sun goes down why doesn’t Hashem pay us a reward every day especially the Rabbis say the ultimate payment will be when Moshiach comes? The answer is we’re not just employees but partners with Hashem. In order to change the world and make it a better place which will be realized when Moshiach comes that will be Hashem’s profit, and our profit will be seeing everything we accomplished However while we’re doing the work until we get there Hashem takes care of everything we need.
