From the reformation came these wonderful truths of scripture :
Sola Scriptura - Scripture Alone
Solus Christus - Christ Alone
Sola Gratia - Grace Alone
Sola Fide - Faith Alone
Soli Deo Gloria - The Glory of God Alone
Unwarranted confidence in human ability is a product of fallen human nature ... God's grace in Christ is not merely necessary but is the sole efficient cause of salvation. We confess that human beings are born spiritually dead and are incapable even of cooperating with regenerating grace. We reaffirm that in salvation we are rescued from God's wrath by his grace alone. It is the supernatural work of the Holy Spirit that brings us to Christ by releasing us from our bondage to sin and raising us from spiritual death to spiritual life. We deny that salvation is in any sense a human work. Human methods, techniques or strategies by themselves cannot accomplish this transformation. Faith is not produced by our unregenerated human nature.
