you dont actually have to persuade them to believe. You don’t need to have an intellectual battle with them. You don’t have to feed them the entire bible and please them to believe, why? IT WILL ONLY CREATE ARGUMENT, CHAOS, MISUNDERSTANDINGS and whatsoever. You know whats the secret way for them to?
your testimony. show them your life, who you were before you met Him and who you are now with God in your life. But its not a guarantee that all people will approve of you and with your God. we are still on earth sweetie, remember that. secondly, just love them, love those people regardless of their belief. And never debate, ang katotohanan hindi dapat pinagtatalunan, dahil ang katotohanan mananatiling katotohanan :)
In short, kung gusto mo silang maniwala na may God, dapat makita nila yun sa buhay o puso na meron ka :)
