SINGING

'Let us remember that the very power of singing was given to human nature chiefly for this purpose, that our warmest affections of soul might break out into natural or divine melody, and that the tongue of the worshipper might express his own heart.' 

Isaac Watts in Bob Kauflin, True Worshippers: Seeking what matters to God, p.109. 

FEELINGS

'Even when reason is bright and the judgement clear, yet it will be ineffectual for any valuable purposes, if religion reach no farther than the head, and proceed not to the heart: it will have but little influence if there are none of the affections engaged.'

Isaac Watts in Graham Beynon, Emotions, p.174.

FEELINGS

'The grave is the only burying place of unruly affections.'

Isaac Watts in Graham Beyon, Emotions, p.163.
