Small Catechism 3
How can water do such great things?
Answer: it is not the water
Indeed that does them
But the Word of God that is
In and with the water
And faith which trusts such Word
Of God in the water
For without the Word of God
The water is simple water and no baptism
But with the Word of God, it is a baptism
That is
A gracious water of life and a washing
Of regeneration in the Holy Ghost
As Saint Paul says, Titus chapter 3
"By the washing of regeneration and
Renewing of the Holy Ghost
Which He shed on us
Abundantly through Jesus Christ, Our Savior
That, being justified by His grace
We should be made heirs according to
Thе hope of eternal lifе"
This is a faithful saying
