According to St. Paul, "Grace" is a free gift from God for the man of faith. It is an unmerited favor that God bestows upon believers, which they do not deserve and cannot earn. Grace is seen as a central concept in Christianity, representing God's love and mercy towards humanity. It is believed that through God's grace, believers can receive forgiveness of sins and eternal salvation. Grace is therefore a fundamental part of Christian theology, and is viewed as a key element in the relationship between God and humanity.
