Hi I am new here.
I think before you can rebuke you need to know the situation and not lead to assumptions.
In my situation I have a baby out of wedlock and I almost left the church cause of it. What people assume is usually totally wrong. I got raped by an ex boyfriend. I avoid certain Christians. At present I am healing but it is hard. What I learnt is grace is kinder. Not everyone needs to know what happened but grace allows me to keep this confidential.
I think there is a scripture " There is no condemnation in Christ
