Thou, even Thou alone

Verse 1
Thou, even thou alone,
O God by nature One,
Infinite in wisdom art,
Jesus to thy Father join’d
Searcher of the reins and heart,
Knowst the hearts of all mankind.

Verse 2
By this thy churches know
Their God reveal’d below,
Sure that thou, O Christ, art he,
God supreme in glorious grace;
Fulness of the Deity
Thee thy saints for ever praise.
