1 John 5:6 (New International Version)
6 This is the one who came by water and blood —Jesus Christ.
Blood, it is said, is thicker than water. This is usually taken to mean that family ties, blood ties, transcend any other relationships. Yet some contend that this proverb has completely reversed from its original meaning. They argue that covenant relationships, sealed in blood, transcend family ties, alluded to in the proverb via amniotic fluid, womb water.
However that may be, believers in Christ are children of God (verse 1). They are born into a spiritual family. Consequently, they love their spiritual siblings and love and respect their mutual Father (verses 1-3). They overcome the world (verse 4), they who believe in Christ (verse 5).
And Christ came by water and blood (verse 6). Jesus’ ministry was bracketed by baptism (by John in the Jordon) and crucifixion (when blood and water came from Jesus’ spear-pierced side). Today on January 2, in our calendar between remembering at Christmas Jesus’ birth and remembering at Easter Jesus’ death, we might pause to consider the whole sweep of Jesus’ life – coming, teaching, healing, suffering, dying, rising, ascending.
And as we pause we might think of our own baptism and the new birth the water of baptism points to and we might think of the communion cup and the blood shed for us and the new covenant that blood inaugurates.
