A monergist is a person who believes that God alone effects a person's salvation. They believe that the Holy Spirit is the only active agent in a person's spiritual rebirth, that the human will is considered spiritually dead and incapable of choosing God on its own until God first steps in to change the person's heart. They believe that saving faith is a gift from God to all whom the Father chooses to become part of the body of Christ. The gift is the Holy Spirit which acts as a portal through which the invisible God the Father enters the being of God the Son, and through which they both enter our beings to change our motivation for living and fill us with love, wisdom, and truth. They believe that all (100%) of the glory for their salvation goes to the Father and to the Son because in 1 Cor 1: 29, no flesh should glory in His presence. That means that no one in heaven can say "I did it!", or "I made the right decision!", or "I did the right things and believed the right things!".
A synergist is a person who believes that salvation involves a cooperative effort between divine grace and human freedom. They believe that God initiates salvation through grace, but the individual must freely choose to accept, respond to, or cooperate with that grace. They emphasize that human beings possess the free will to either assent to or resist God's salvific grace. They believe that they should get some of the glory for their salvation if they accept God's grace.
