I’ve recently started reading Ralph Erskine’s Gospel Sonnets to my four children with great profit. Written in 1720, this book combines incredible theological precision with beautiful poetry. Thanks to Google, you can now read or download a pdf copy of this hard to find book. Here are a few lines dealing with both justification and sanctification:

The believer, being married to Christ, is both justified and sanctified

Proud nature may reject this gospel-theme,
And curse it as an Antinomian scheme.
Let slander bark, let envy grin and fight,
The curse that is so causeless shall not light.
If they that fain would make by holy force
‘Twixt sinners and the law a clean divorce,
And court the Lamb a virgin chaste to wife,
Be charg’d as foes to holiness of life,
Well may they suffer gladly on this score,
Apostles great were so malign’d before.

When as a cov’nant stern the law commands,
Faith puts her Lamb’s obedience in its hands:
And when its threats gush out a fiery flood,
Faith stops the current with her victim’s blood.
The law can crave no more, yet craves no less,
Than active, passive, perfect righteousness.
Yet here is all, yea, more than its demand,
All render’d to it by a divine hand.
Mankind is bound law-service still to pay,
Yea, angel-kind is also bound t’ obey.
It may by human and angelic blaze
Have honour, but in finite partial ways.

Thus doth the Husband by his Father’s will
Both for and in his bride the law fulfill:
For her, as ’tis a covenant; and then
In her, as ’tis a rule of life to men.
First all law-debt he most completely pays;
Then of law-duties all the charge defrays.
Does first assume her guilt, and loose her chains;
And then with living water wash her stains:
Her fund restore, and then her form repair,
And make his filthy bride a beauty fair;
His perfect righteousness most freely grant,
And then his holy image deep implant;
Into her heart his precious seed indrop,
Which, in his time, will yield a glorious crop.
But by alternate turns his plant he brings
Through robbing winters and repairing springs.
Hence, pining oft, they suffer sad decays,
By dint of shady nights and stormy days.
But blest with sap, and influence from above
They live and grow anew in faith and love;
Until transplanted to the higher soil,
Where furies tread no more, nor foxes spoil.
