The gospel conviction of Martin Luther.
Christ fulfil the law for me and the merit necessary for my justification. This is the ground not only of my justification, but also of my assurance of salvation.
If I must wait unit I cooperate with the righteousness of Christ infuse within me, to the degree that I become inherently righteous, I despair of ever attaining salvation. This is not gospel or "good news"; It is bad news.
I love The church. It is the body of Christ. It nurture my soul and aids in my sanctification. But the church cannot redeem me. Christ and Christ alone can save me.
The sacrament are precious to me. They edify and strengthen me. But they cannot justify me.
