Gopolang,
Thanks so much for your question. I have no formula to teach you. But I will say this. Jesus always first talked about the Kingdom of Heaven being at hand and the need to repent. Repent doesn’t just mean confess your sins. It means to change your whole way of thinking from a self-centered, material perspective on life with the Kingdom of Heaven off in the future to a spiritual, God-centered perspective with the Kingdom of Heaven here and now. You can’t see that it’s here if you don’t change the way you see and think.

As for some specific Scriptures, I would suggest studying all of Jesus’ parables. And even make up some of your own if something comes to you. Jesus used everyday topics and situations to illustrate what the Kingdom was like. When you tell people how wonderful the Kingdom is, they want to be part of it out of love. You don’t have to scare them into it. That never really works, although some people use this approach and believe it is the best. We want people to obey God and follow Jesus because of love instead of fear.

Let people know how much God loves them. That’s ultimately what Jesus did. You can too.

I hope this is helpful.

Blessings,
James
