On Faith, as the best Wedding-Garment

Lord, enrich my heart with Faith, as the best
Wedding-Garment, for this most sacred Feast;
Left doubting of thy mercy should create
More sin, to raise and aggravate thy hate,
Instead of pardon for those Crimes are past,
And leave no remedy for this at last.
Such doubting strikes at thy Omnipotence;
To flight thy Mercy is a great offence,
Next to presuming on't with insolence.
I therefore beg thy holy Spirit may
Direct my Faith, and teach me how to pray.
