A cornerstone topic that permeates the pages of Science and Health with Key to the Scriptures is the existence of a supreme, infinite God. Eddy characterizes God with qualities of being all-loving, omnipotent, and possessing infinite goodness. As a result, he can be accessed by demonstrating active faith in him and sincerely praying to him. Eddy believes that humans are the likeness and image of God. By drawing closer to God, individuals move to a higher plane of living and develop inner peace and comfort. God’s divine laws are applicable to each person every day.
Eddy pleas for people to follow the example of Jesus Christ and strive to live as he did every day. She promotes the principle of treating others the way we would like to be treated. Jesus Christ is the Son of God who carried out the Atonement, which was necessary to overcome sin and reconcile humankind with God. Eddy reminds the reader that this supreme act is evidence of God’s divine, efficacious love. Through the crucifixion and resurrection of Christ, death is overcome. Each individual can rise again and live eternally.
Science and Health with Key to the Scriptures emphasizes the necessity for individuals to study the Bible on a daily basis. Because the true nature of each individual is spiritual, spiritual nourishment must be provided from divine sources, which include sincere prayer to God, faithful study of the Bible, and living by God’s words. Eddy explains the application of biblical teachings to the practice of everyday Christian living and to working out one’s eternal salvation. Reading the Bible strengthens one’s trust in the power of prayer and the power of God and makes Christ’s teachings practical in the world today.
