"Having given them grace, I will give them a crown."
After "consuming" quite a number of Charles Spurgeon's sermons, I finally decided to read his biography, and found this quote simply encouraging,
"I think how surprised some of God's people will be" he exclaims, "when they get to heaven. They will see the Master and He will give them a crown.
'Lord, what is this crown for?'
'That is because thou didst give a cup of cold water to one of my disciples.'
'What, a crown for a cup of cold water?'
'Yes,' says the Master, 'that is how I pay my servants. First I give them grace to give the cup of water, and then, having given them grace, I will give them a crown.''"
