What does the Bible say about the double cure?

The double cure is illustrated clearly in John 19:34, where blood and water flowed from Jesus' side after His death. This signifies that Christ not only provides salvation from the guilt of sin through His blood but also offers cleansing and righteousness through the water, symbolizing the sanctifying work of the Holy Spirit. As stated in Romans 3:23, all have sinned and deserve death, making the need for both the atoning sacrifice and the impartation of righteousness vital for our salvation. The concept is encapsulated in Hebrews 10, where we see that Jesus' sacrifice perfected forever those who are sanctified, highlighting the need for both justification and sanctification in the believer's life.
