If you were to hear a message from heaven, what would you expect it to say? Would it say, "Love!" or "Go to church!" or "You're doing great!" or "Behave"? A lot of people have different opinions of the message our society needs, but the message God sent through John the Baptist to prepare the hearts of the people for the Heavenly Kingdom was, "Repent!" This message, recorded in Matthew 3:2, was the first public announcement God had made in 400 years.
If you were to take a road trip to Canada, which route would you take? I've heard people describe their plan on getting to heaven like a road trip to Canada: there's this large destination, and as long as you keep north, you can't go wrong. You can pick your route according to what you want out of the trip; do you want the fastest route, or the best scenery through the forests? The shortest mileage, or novelty shopping in Thief River Falls or Bemidji?
"I lift up my eyes to the hills — where does my help come from?" Psalm 121:1 People expect different things from God. Some view him as a magic lamp to rub when they need a genie; some hang a cross from their keychain for good luck like a rabbit's foot, others never talk to him at all until they need out of a tight fix. These views of God lead to frustration over the 'silence from heaven' this kind of relationship often produces, but the writer of Psalm 121 gives testimony that for those who walk with God, he is never far during times of trouble.
