Thomas Watson in A Body of Divinity:
We glorify God by working out our own salvation. God has twisted together his glory and our good. What an encouragement is this to the service of God, to think, while I am hearing and praying, I am glorifying God; while I am furthering my own glory in heaven, I am increasing God’s glory.
Would it not be an encouragement to a subject, to hear his prince say to him, You will honour and please me very much, if you will go to yonder mine of gold, and dig as much gold for yourself as you can carry away? So, for God to say, Go to the ordinances, get as much grace as you can, dig out as much salvation as you can; and the more happiness you have, the more I shall count myself glorified.
