一 今日何日！我意立定，揀選我神和我救主！
我心歡樂如火熒熒，將此歡樂到處傳述。
（副）快樂日！快樂日！耶穌救我，使我歡樂！
贖罪寶血洗我罪惡！生命活水解我乾渴！
快樂日！快樂日！耶穌救我，使我歡樂！
二 快樂之約繫我於主，惟祂配受所有愛敬；
願我歌唱讚美不住，當我向主寶座前行。
三 此約既定，永不反悔，主今屬我，我也屬主；
祂既吸引，我必跟隨，歡然答應祂的招呼。
四 前我二意，今可安定，讓主作我惟一中心；
注定於祂，永不別傾，有祂，就有一切福分。
五 今在主前立定此意，更願此意與日俱新；
直到臨終雙目垂閉，進入永遠與祂更親。
1. O happy day that fixed my choice
On Thee, my Savior and my God!
Well may this glowing heart rejoice,
And tell its raptures all abroad.
Refrain
Happy day, happy day,
When Jesus washed my sins away!
He taught how to watch and pray,
And live rejoicing ev'ry day;
Happy day, happy day,
When Jesus washed my sins away!
2. O happy bond, that seals my vows
To Him who merits all my love!
Let cheerful anthems fill His house,
While to that sacred shrine I move.
3. 'Tis done: the great transaction's done;
I am my Lord's and He is mine;
He drew me, and I followed on,
Charmed to confess the voice divine.
4. Now rest, my long-divided heart;
Fixed on this blissful center, rest;
Nor ever from my Lord depart,
With Him of ev'ry good possessed.
5. High Heav'n that hears the solemn vow,
That vow renew'd shall daily hear,
Till in life's latest hour I bow,
And bless, in death, a bond so dear.
