1 John 1:7
but if we walk in the Light as He Himself is in the Light,
we have fellowship with one another,
and the blood of Jesus His Son cleanses us from all sin.
At first it seems to us, to be a contradiction: blood and purification.
Blood makes nasty, indelible stains, doesn’t it?
Yet the apostle speaks here very emphatically about the cleansing effect of the blood shed on Golgotha.
That blood does not take away ordinary filth, but the filth of sin.
While the temple was still there, the people of Israel could see daily in God’s house that blood had to be shed to reconcile sinners to God.
Sin is not ordinary filth, it is a deadly disease.
Instead, the sacrificial lamb had to give his life to save a guilty human child.
The Lamb of God has come and has donated His blood.
The big question is: Do we want to be cleansed by Him?
Or do we try to cleanse ourselves with some pious or very brazen remarks?
Do you hear how gloriously it is preached to us by John?
Of all sin, therefore also of the greatest, sin.
