A.W. Tozer emphasizes that while the gospel brings joy and blessings to believers, it also serves as a warning to those who do not obey its message. The Cross represents good news for the repentant, but it also highlights the consequences of sin, righteousness, and judgment for the impenitent. The gospel can be received either as a powerless word or as a powerful truth that transforms lives, shifting one's identity from Adam to Christ. This transformation brings a new Spirit into the believer's life, resulting in a complete renewal of their being. Tozer calls for an understanding of the dual nature of the gospel, urging listeners to embrace its power for true change.
