God says

When we meet him

As Christians we should not be afraid of death or rapture because it is the way we can go and meet our heavenly father.
Our father sent us on earth so we can bring more people when coming so we must try and bring people along with us to heaven so when we go we don't disappoint our father in heaven.

Do you want to disappoint your father in heaven?

Go therefore and make disciples on the nations, baptizing them in the name of the Father the Son and the Holy Spirit, teaching them to observe everything that I have commanded you.
                 Mathew 28:29-20

Let's all try to tell people the Good news.
