John Newton - Philadelphia

Thus saith the holy One, and true,
To his beloved faithful few;
Of heav'n and hell I hold the keys,
To shut, or open, as I please.

I know thy works, and I approve,
Though small thy strength, sincere thy love;
Go on, my word and name to own,
For none shall rob thee of thy crown.

Before thee see my mercy's door
Stands open wide to shut no more;
Fear not temptation's fiery day,
For I will be thy strength and stay.

Thou hast my promise, hold it fast,
The trying hour will soon be past;
Rejoice, for lo! I quickly come,
To take thee to my heav'nly home.

A pillar there, no more to move,
Inscribed with all my names of love;
A monument of mighty grace,
Thou shalt for ever have a place.

Such is the conqueror's reward,
Prepared and promised by the Lord!
Let him that has the ear of faith,
Attend to what the Spirit saith.

John Newton
