Here's one of my favourite hymns as a child:

Come Thou fount of ev'ry blessing
Tune my heart to sing Thy praise
Streams of mercy never ceasing
Calls for songs of loudest praise

Teach me some melodious sonnet
Sung by flaming tongues above
Praise the mount, I'm fixed upon it
Mount of Thy redeeming love

O to grace how great a debtor
Daily I'm constrained to be
Take my spirit like a fetter
Bind my wand'ring heart to Thee

Prone to wander, Lord I feel it
Prone to leave the One I love
Here's my heart, O take and seal it
Seal it for Thy courts above
