AFAIK Russia has been a trustworthy gas supplier and it would be economical suicide if they proved not to be trustworthy.
Free trade requires easy substitutes to remain "free" and opponents of this plan mostly think that energy markets don't work like that because of high switching costs. Germany can not just spin up new nuclear plants or easily buy electricity from neighbors past a certain amount of it's usage. I don't know enough to know if this angle is correct.
Germany's alleged dependence on Russian gas is mostly a fairytale of US propaganda.
The middle east is another potential supplier and Italy, for example, get their gas from Africa. Germany also has the biggest gas storage capacity in Europe and the gas tanks are usually filled quite well before winter (>95%). Not this year though, because the MBAs took a gamble on Nord Stream 2 going operational and lost the wager, resulting in soaring gas prices all across Europe.
You also need to keep in mind that natural gas is not solely used for heating homes, but also industrial processes and generating electricity, among others, which could be reduced or stopped if it really came down to it.
In short: Russia turning off the valves would be more of an inconvenience than the life-threatening situation it is often claimed to be. But personally I don't see that happening, as the Russians have been a very reliable supplier for decades.
But during a crisis, which one do you think will collapse first?
1) Germans freezing to death without energy to heat themselves and move their economy
2) Russians drinking vodka
