This quote by Jonathan Edwards is breathtaking:
Make God the peculiar object of your praises. The doctrine [of electing grace] shows what great reason you have to do so. If God so values you, set so much by you, has bestowed greater mercies upon you than on all the ungodly in the world, is it too little a requital for you to make God the peculiar object of your praise and thankfulness? If God so distinguishes you with his mercies, you ought to distinguish yourself in his praises. You should make it your great care and study how to glorify that God who has been so peculiarly merciful to you. And this, rather, because there was nothing peculiar in you differing you from any other person that moved God to deal thus peculiarly by you: you were as unworthy to be set by as thousands of others that are not regarded of God, and are cast away by him forever as worthless and filthy.
Quoted in Chosen For Life by Sam Storms
If you are a Christian, it is because God has shown you peculiar mercy. He chose to pour out mercy upon you, not because of anything good in you, but because of His sovereign grace. Why did he save you and not your neighbor? Why do you know Christ, but your parents don't? Because for some reason, God chose to pour out lavish mercy upon you. This should cause our hearts to explode in loud praise for the Lord. Take time today to sing the praises of the God who saved you.
