Your unsaved family and friends are not interested in your changed beliefs. Calling them 'wishy washy' is an attack on you / Jesus in you. Jesus / the light in you causes offence and does not change. You either have Him or you don't.
They do not care about you better explaining anything. Though it is a foot in the door .
I would share the basic teaching / elementary / unchanging principles of Christianity in Heb 6.
I know they are not interested today...but my accountability to God is to give them the Word anyways. Who knows? Maybe I'm planting seeds, someone else will come along and water them...and God will reap the harvest...unbeknownst to me until I get to heaven!
