Who has experienced these decisive events and how have they shaped our lives?
They bring newness to our lives and are gifts - although sometimes it may take us a while to realize this. Abraham and Moses lived through decisive events that they did not expect. God wanted Peter to realize that the Gospel is for everyone and not just those who followed the rules.
His message is to love one another, to reach out and to demonstrate true care for others.
Sometimes if we act in God's love then the rules follow.
