Originally coming from a charismatic environment, I was won over to Lutheran doctrine because that's where I found the Gospel to be the clearest. Specifically, in its confession that salvation is entirely from God, but damnation entirely from us.
Now, our Roman Catholic friends will certainly disagree with this, but from a Lutheran point of view, doctrinally and historically speaking, it is the Evangelical Lutheran church that is the true "Roman" church. The desire of the reformers was not to create an original church, but rather to conservatively reform and revert to the original doctrines that were once held by the early church; the apostolic faith. In this respect, both Anglicans and Lutherans can claim apostolic succession (though this can be understood in many different ways).
In short though, Lutherans confess: "That one holy Church is to continue forever. The Church is the congregation of saints, in which the Gospel is rightly taught and the Sacraments are rightly administered.", carefully not making a claim that the Lutheran church alone is the only true church. For more info on this, I would read up on the theology of the "visible and invisible church". viz. the visible church including all members, whether true or not. And the invisible, including only true believers. Traditionally, the Roman Catholic Church reject this and identify with the invisible church (in visible form), but Lutherans hold that the Holy Church's members can be found in many different branches of Christendom, even where the Gospel is not preached clearly, or where the Sacraments are not properly understood, because salvation is not a matter of nominal membership, but correctly of God's grace, apprehended through faith.
