While it is true that Lutheranism is not Calvinism, nor ever can be, both find their soteriological basis within Augustinian theology which is quite monergistic. Luther developed that monergism into a sacramental form such that an individual who has been baptized will be saved - not because God necessarily elected them from the foundation of the world, but simply because God, who cannot lie, has stated that everyone who is baptized will be saved. Thus, it is God who saves and does so according to His word and not according to the will of man.
Partly true. God did elect them from the foundation of the world. The difference is how Lutherans understand election. Election is neither secret, nor does it involve God picking and choosing who will (and conversely won't) be saved. Instead election is the entire proclamation of the Gospel by which God, out of His grace and kindness toward us, has reconciled us to Himself through Jesus Christ, and thus made clearly known through Word and Sacrament. Such that the baptized can know this: They are elected by God, and they can know this because of their baptism. Election is not to be understood as God saying "I save this person, but not this other person"; but rather that God saves, and God saves because it is His gracious will and pleasure to redeem, save, and reconcile the whole human race through Jesus Christ. Yet nevertheless man may resist God's grace and so deprive himself of God's free gift.
It is therefore a "double monergism" if you will.
Salvation does not come from the will of sinful man, but the will of God.
Damnation does not come from the will of God, but the will of sinful man.
So that it is, though God has made justification for all by the cross (Romans 5:18), nevertheless not all necessarily will be saved, for man in his sin, despising God and at enmity with God, prefers darkness over the light. As it is written in John chapter 3, that God so loved the world that He gave His only-begotten Son, that whosoever believes upon Him will not perish but have everlasting life, for Christ did not come to condemn, but to save; yet there is the condemnation already, men loved darkness over the light, for their deeds were evil.
God is pro-active in saving us. That's what Word and Sacrament are about. God is pro-active, unwilling that any should perish, but that all come to everlasting life through Christ our Lord. God doesn't sit idly back waiting for us to come to Him, but rather comes to us, meets us, God comes down.
Throughout the entire Bible, God is always coming down. God comes down to rescue, God comes down to save, God comes down to heal. God came down to meet Abraham, God came down to rescue Israel from Egypt, God comes down. In the Incarnation, in the Scriptures, in the preaching of the Gospel, in the Sacraments. God comes down; we don't go up.
It's not up to us to meet God that He might reward our efforts with salvation and the promise of heavenly bliss. Rather, God comes down, and says, "See here what I do, trust this". For the Law says "Do this" and it is never done; but the Gospel says, "Trust this" for it is already done. For the work is already done and accomplished, Christ has already fought and won, by His obedience, His passion, His resurrection.
