Spurgeon on Assurance of Salvation

Beware, I pray thee, of presuming that thou art saved. If thy heart be renewed, if thou shalt hate the things that thou didst once love, and love the things that thou didst once hate; if thou hast really repented; if there be a thorough change of mind in thee; if thou be born again, then hast thou reason to rejoice: but if there be no vital change, no inward godliness; if there be no love to God, no prayer, no work of the Holy Spirit, then thy saying “I am saved” is but thine own assertion, and it may delude, but it will not deliver thee.

—Charles Spurgeon
