I was surprised to read at how jealous and distrusting goatherder Peter was. Anyone who drew Heidi’s attention from him was a target for his wrath.
Heidi then also is able to take what the grandmamma has taught her and is able to help her Grandfather restore his relationship with God and with mankind down the mountain. Her grandfather’s heart is softened towards God and humankind. She tells grandfather that from now on they will pray every day and give thanks so they will not forget what God has done and so God will not forget them. Grandfather asks what if we forget him, Heidi replies then God lets the man go his own way. If he complains no one has pity on him for he forsook the Good Lord first, now his is forsaken of God, who alone could help him. Heidi then goes on to tell the grandfather of the prodigal son and how the father welcomes back those to come back to him. Grandfathers heart is softened and he returns back to God.
