I am a deeply conservative Christian and married into a family that is mostly more progressive. My sister-in-law was recently divorced and is now dating a trans-person. She and I have had extensive conversations about why I am so against this relationship but have stayed close because I have always done it with love. My husband and I have reassured her that if we are to cross paths with this person we will be kind and respectful. I truly believe Jesus would scoff at us being unkind to a person plagued by sin. We are still human beings who sin daily and are constantly striving to be better.
I really feel like we have handled it correctly but now I am coming to a crossroads.
She is bringing this person to meet her family on Saturday and my children and I are expected to be there.
Do we go or stay out of it?
If we go are we reaffirming a sin or showing approval of it? If we don’t go are we showing the hate that Jesus constantly warns us against?

i’m 26 and found out recently that my dad is not my dad. we had never had a relationship so loosing whatever connection we had felt like no big deal but i have been really lost about connecting with my bio-dad.
when we met, i immediately could have told you he was my dad. for as long as i can remember, i had questions about why i didn’t look like my dad and this cleared them up haha.
now, we have set another day to meet up and for mw to meet my siblings. we talk weekly but i feel like we are not getting anywhere relationship wise.
i really want to know my dad. am i reading too much into this and expecting too much?
i have literally never been more lost.
