Matthew 6:1-7 is a relevent scripture (does quoting scripture make me super spiritual, lol?)
Basically, don't do things to be seen by men. If you do that, then you get your reward in full.
However, it tells us only what we can do, not what we can expect others to do. I thnk the advice about looking at those people as God's children is really helpful. I am assuming that they are warm-hearted and genuinely caring, mission-focussed, etc etc.
The other useful bit of scripture is about the Body of Christ. We aren't all the same, we were never meant to be, but together, we are perfection. It is not easy to be a little toe, when someone else is a beautiful eye - but that may be the plan that God has for us. Looking through the bible, there are many bible heroes who were low on glamour.
We can take a lesson from our super spiritual sisters. They don't know their bible quotes for no good reason. The have read their bibles daily, alongside commentaries. They have faithfully attended bible studies and hung off every word of their equivalents back then. They have a prayer life to die for.
They shouldn't make you feel bad for not having the same bible study and prayer disciplines, but surely they should be allowed to witness and testify? They need to encourage you in your Christian journey, but not judge. How you respond is a very fine line. At the end of the day, you should not be judging them, which is exactly what you are accusing them of. If you see a speck...take the plank out of your own eye (owtte).
