Isaac was born in Russia to devout Jewish parents. He chronicles his early years and his studies. One great question consumed him, ‘If death should summon me, will I be unworthy to stand before God unpardoned?’ Thus Isaac embarks on a lifetime journey. Troubles plaque him, but he has the love and support of his family. Then he meets a fellow Jew in a Christian church. His progress is related through letters to his father and the replies he received. The conclusion of the book is a series of fragments from his wanderings in the land of his fathers, Palestine, as a missionary. His visits to landmarks and special sites are accompanied by adventure and faith.
