Emma, now the 28 yr. old daughter who was to save them had one little problem - a lack of faith to believe what was written in the storybook, that all the people in the town were once beloved storybook characters in another land or parallel universe. The evil queen who put the curse on everyone knew love once, but because her heart was broken, it was her life's mission to ruin everyone else's happily ever afters, especially Snow White's. What she couldn't see was that ruining everyone else's happiness did not really create happiness for herself.
She was the mayor in this parallel world, and knew everything about everyone, and how to make life miserable for them. Her adopted son, who was actually Emma's birth son (and Snow White and Prince Charming's grandson), read the storybook, so knew how everything fit together, and how the town could be saved from the curse. As Emma started intervening in the town and became the sherriff, things started to change and the curse started to weaken, and memories started to come back, as well as happiness. The boy had great faith in what was written in the book, as it related to what he could clearly see in the people and the world around him. Emma, however, could not see past the here and now, the cold, harshness of reality. One of the greatest challenges was to get Emma to see what was right in front of her with eyes of faith, but she chose to disbelieve. The truth could be right in front of her face, and yet she refused to see it.
This reminds me of this present world. This world is not our true home, the Bible says, but we are strangers and foreigners. 1 Peter 2:11: "Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul."
The Bible tells of a rich man who died. He asked Abraham to send someone back to the earth to warn his family about hell, because surely if someone came back from the dead to tell them about it, they would believe and could avoid that eternal place of torment. However, Abraham told a very sad truth in Luke 16:29-31:
