"Fear is the opposite of faith," Someone once said. I agree with that statement. Christians do not worry about tomorrow because Jesus made it clear that while he did not know the date or time of the end, we can be sure God's got the final say on when all we know is over. (Matthew 24)
The words of Jesus we usually read at funeral services are appropriate here. Jesus was comforting his disciples when they began to realize his end was near.
Do not let your hearts be troubled. Trust in God; trust also in me. My Father’s house has plenty of room; if that were not so, would I have told you that I am going there to prepare a place for you? And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am.You know the way to the place where I am going. (John 14:1-4)Jesus promised that whatever we face here, we can trust He has a place beyond here with Him. Now, that's good news in the face of hype about the end of all things.
