Covenanting to serve the Lord

Come, ye that fear the Lord,
And love Him while ye fear;
Come, and with heart and hand record
Your vow and covenant here.

Vow to be His alone
Who bought you with a price;
Now render back to God His own,
By free-will sacrifice.

Here to His altar brought,
Your covenant renew,
To be in word, and deed, and thought,
Faithful to Him and true.

And true and faithful He
To you will ever prove,
Though hills were swept into the sea,
And mountains should remove.

Then be His law our choice,
The joy of young and old,
As sheep that hear their shepherd's voice,
And follow to the fold.

So shall His staff and rod
Conduct us and defend:
God is a covenant-keeping God,
And loves unto the end.
