George Herbert, one of the metaphysical poets influenced by John Donne in the 17th century, left behind his only book of religious poetry, The Temple. His religious belief was based on Calvinism, Protestant Reformation, as well as the traditional medieval Scholastic philosophy. He learned from the medieval Scholastic philosophy that the Almighty God or the Creator has an invisible power over all space and time and has personal character. Influenced by Calvinism, he also believed in the doctrines of predestination, the irresistibility of grace, and justification by faith. The Temple is a confessional record of his deep thoughts on and strong wish for God`s grace and providence. He wanted people to step closer to God`s love toward human beings irrespective of their religion and could have real freedom, peace and joy. The aim of this paper is to explore God`s Grace and Man`s Rationalism in Saving, focusing on such poems as "The Altar," "Redemption," "Thanksgiving," "The Reprisal," "The Holdfast," "The Pearl," "Dialogue," "Love (3)," In these poems Herbert criticizes the rational thinking that human being could participate in the process of redemption and contends that redemption is only possible by God`s grace. He argues that human being should come to God as the way they are and can be redeemed only by God`s grace. (Paichai University).
