What does it mean that life is given when the blood is applied?

In Exodus 12, it was vital for the Israelites to not only slay the lamb but to apply its blood to their doorposts to ensure their protection from the death judgment. This act symbolizes the necessity of faith and acceptance of Christ's sacrifice for the forgiveness of sins. In a Christian context, having the blood of Christ applied means that the individual has internalized faith in His sacrificial death and resurrection. This belief grants spiritual life, as the Holy Spirit applies the redemptive work of Christ’s blood, ensuring that believers are spared from judgment and granted eternal life with Him. Thus, without faith, the application of His blood does not occur, emphasizing that only by trusting in Christ can one receive this transformative life.
