Charles Spurgeon Commentary 1 John 5:6

"This is he that came by water and blood, [even] Jesus Christ; not with the water only, but with the water and with the blood." — 1 John 5:6 (ASV)

This is he that came by water and blood, even Jesus Christ; not by water only,–

Cleansing us concerning our lives: not by water only,–

But by water and blood.

The blood which takes away the guilt of our offenses. There is a double cure for us in Christ Jesus our Lord: first, the putting away of all our past guilt; and then, the delivering of our hearts from defilement, so that we live in a holy way.
