Applying the Blood is a devotional and theological exploration of the redemptive power of Jesus Christ's sacrifice, focusing specifically on the spiritual significance of His shed blood. The book emphasizes not only understanding Christ's atonement intellectually but actively "applying" His blood by faith in daily life for victory, freedom, healing, and restoration.
The central theme is drawn from Scripture's teaching that "without the shedding of blood there is no remission of sins." The author explains how the Old Testament sacrificial system foreshadowed Christ's ultimate sacrifice. Just as the Israelites applied the blood of the Passover lamb to their doorposts for protection, believers today must spiritually apply the blood of Jesus to experience salvation and protection from spiritual destruction.
The book carefully examines the specific sufferings of Christ and assigns spiritual meaning to each wound. The crown of thorns represents deliverance from the curse that came through Adam's fall, particularly the curse affecting the mind, toil, and oppression. Christ's pierced hands redeem the works of humanity, restoring purpose and blessing to what believers put their hands to. His pierced feet signify restored dominion and authority, reversing the loss of rule given to Adam. The stripes on His back are associated with healing—both physical and spiritual—fulfilling the prophecy that "by His stripes we are healed." The spear wound in His side speaks of cleansing and the birth of the Church, as blood and water flowed out.
Another major theme is covenant. The author teaches that the blood of Jesus established a New Covenant between God and believers. This covenant guarantees forgiveness, justification, reconciliation, and access to God. Rather than living in guilt or condemnation, Christians are encouraged to approach God boldly because the blood has satisfied divine justice. The book stresses that Satan's primary weapon is accusation, but the blood of Jesus silences those accusations. Believers overcome "by the blood of the Lamb and by the word of their testimony."
