The Critical Difference Between Monergism and Synergism
This is the one point that monergism establishes and synergism in all its forms denies: namely, that sinners are impotent to lift a finger toward their own salvation, but that salvation, from first to last, whole and entire is of the Lord Jesus Christ, to whom be all glory for ever; amen
Remember, divine election, by itself, has never saved anyone. It marks out certain individuals for salvation; it is God's "blueprint" of what he intends to do in time through the redemptive work of Jesus Christ and the regeneration of the Holy Spirit. God the Father elects, the Son redeems them, and the Spirit applies the work of Christ to the same. The Trinity works in harmony to bring about God's purposes of election... and He gathers them through the preaching of the gospel, the seed which the Spirit germinates and brings to life. Again, salvation is of the Lord.
Synergists teach that 'salvation depends on human will', but the Bible teaches that 'it depends not on human will or exertion, but on God, who has mercy." (Rom 9:16) and that we "were born, not of...the will of the flesh nor of the will of man, but of God. (John 1:13)
