One of my proudest moments so far was taking part in occupying a piece of disused land, erecting an old circus tent and setting up smaller tents within it, to save around 30 people from my local homeless population from freezing to death during a 2 week long cold snap.
We housed and fed them during that time, using only donated resources, whatever food we could safely prepare from dumpster diving and we made those meals on an old army surplus field kitchen.
We even got the city government to chip in with resources after laughing their representative away from the lot, when he tried to chastise us for doing his job for free, while offering no alternatives to solve the problem himself.
The only thing you need to do to be Christlike is to notice a problem in your community, take responsibility for it and then act to solve it while inviting everyone to pitch in with kindness.
If God is the epitome of good, you don't need to invoke him while doing good. If he exists he will see the service for good people voluntarily engage in and might even credit people who do it without the premeditation of wanting to get into his good books a tiny bit more.
I don't think there are many people to save.
Dude, all you have to do to find people in need is exit your home and go looking for 15 minutes. There is ample opportunity to actively do good in every single human settlement on this planet.
You're either ascetic or not. You either live modestly or you're part of the world. We ascetics will be rewarded, but not because we deserve it, but because we loved God and trusted him even when he put us through perilous times and painful times.
Damn, this is like iron age slacktivism, where you just change your profile picture to support the current thing, but don't actually do anything to better the lives of people.
It's just a huge cope for allowing yourself to do nothing and claiming that god will reward you for it.
You're a poser.
