The believer’s rest.
LORD, I believe a rest remains
To all thy people known;
A rest where pure enjoyment reigns,
And thou art loved alone:
2 A rest where all our soul’s desire
Is ﬁx’d on things above;
Where fear, and sin, and grief expire,
Cast out by perfect love.
3 O that I now the rest might know,
Believe, and enter in:
Now, Saviour, now the power bestow,
And let me cease from sin.
4 Remove this hardness from my heart;
This unbelief remove :
To me the rest of faith impart,—
The Sabbath of thy love.
Methodist Episcopal hymnal (1870 edition)
This marvelous hymn is based on the rest mentioned in Hebrews 3 and 4, which is intended to be experienced in this life, not just in the coming one. That was the driving force behind the Methodist Revival—heart holiness, a rest in the finished work of God. It wasn't a legalistic set of rules to follow—no whitewashed tomb for the Wesley brothers, they had already tried that—but a heart washed clean and made anew by the power of the Holy Spirit.
Coupled with that was their belief that a person should feel/experience the witness of the Spirit that they were a child of God. They were sure (as am I) that you cannot encounter the living God and not come away knowing it and having been changed.
Hmynary.org adds a fifth verse that is also worthwhile:
5 I would be Thine, Thou know'st I would,</idle musing>
And have Thee all my own;
Thee, O my all-sufficient Good!
I want, and Thee alone.
