Well, they need to first know I am a universalist.
I asked them if they are willing to be open minded and do a bible study with me and I then them first the Gospel of Grace which sets us free from the Law of Moses and more specifically, we are gentiles not even under their Law. Then I show them that as Gentiles we are grafted in by Faith of Christ and then show them that all sin of those Under the Law is gone in Christ. Then I show them if those under the Law are forgiven, how much are those who were never under the Law forgiven for that which there is no law against? Then I share the love of Christ and show them everywhere in Scripture (100+) where all are promised salvation and then demonstrating that God is omnipotent, omniscient, omnipresent in all things, show them when God makes a promise He never fails.
Even then, they are the ones who have to insist on getting to know what I believe, otherwise it is just a waste of my time to share knowledge they are not wanting to hear.
Proverbs 1:7
The reverence of the LORD is the beginning of knowledge; Fools despise wisdom and instruction.
Proverbs 8:12
āI, wisdom, dwell with prudence, And I find knowledge and discretion.
