Spurgeon's Prayer of Consecration

Charles Spurgeon was saved on January 6, 1850, and on February 1 he wrote the following prayer of consecration:

O great and unsearchable God,
who knows my heart, and tries all my ways;
with a humble dependence upon the support of Your Holy Spirit,
I yield up myself to You;
as Your own reasonable sacrifice, I return to You Your Own.
I would be for ever, unreservedly, perpetually Yours;
whilst I am on earth, I would serve You;
and may I enjoy You and praise You for ever!
Amen.
