I wonder how long a man ought to thank God for forgiving his sins? Is life long enough? Is time long enough? Is eternity too long? How long ought a man to thank God for saving him from going down to hell? Would 50 years suffice? Oh no, that would never do, the blessing is too great to be all sung of in a millennium. Suppose you and I never had a single mercy except this one, that we were made the children of God and co-heirs with Christ Jesus – suppose we had nothing else to enjoy! We ought to sing about that alone forever and ever.
~ Charles Spurgeon (1834-1892)
