Arminianism is a theological perspective within Christianity that emphasizes free will and God's grace. It was developed by Jacob Arminius, a Dutch theologian, in the late 16th century. Arminians believe that individuals have the ability to choose or reject salvation, contrasting with the idea of predestination found in Calvinism. Central to Arminianism is the belief that God's grace is available to all people, enabling them to respond to His call. This view maintains that while God is sovereign, He allows human beings to exercise their free will in accepting or rejecting His offer of salvation.
