What convinced Johann to go to America? When Pastor Vogle told the family that each member of the party (# of people in the family)would each get 50 acres for free. So if each family member put their land together they would have 450 acres for free. It was more land then any land you could get in Germeny back then, and even if you did it would coast a lot of money.
How did Johann feel about the decision later? I would say that he enjoys it because he said that his children loved the farm land and he even loved it. In the end he calls it the Holy Expieriment was working, and by that I think he means that it was a beter idea to move to the the Knew World then he thought it would be.
