Why is the blood and water from Jesus' side significant?

The blood and water that flowed from Jesus' side after He was pierced hold deep theological significance. The blood represents Christ's atoning sacrifice for sin, fulfilling the requirement for redemption, as outlined in the Passover observance where the unblemished lamb's blood protects from judgment (Exodus 12:13). The water symbolizes spiritual cleansing and regeneration, aligning with the necessity of being born again. This duality addresses both the guilt of individual sins and the inherent sinful nature, illustrating the comprehensive salvation provided in Christ as affirmed in Titus 3:5. Together, these elements reflect the fullness of salvation that Jesus accomplished on the cross.
