That's a word we find a lot in the gospels. Immediately , they got up and left everything and followed. Immediately , in other stories, people were touched, and healed. Immediately , their eyes were opened. In the gospel, there is always that sense that now is the time.
Today is the day.
Here is where it all happens. And second, I want to ask what it means when it says that they left everything , to follow. I guess that literally means that they left everything. Their boat, their nets, their families, the works. They left it all behind, and they tagged along.
