A little late on this, been in Haiti. But here are some good resources for further study on the doctrine of election and God’s sovereign purpose in Salvation for those who want to further explore the topic.
Chosen by God by R. C. Sproul – In my opinion the absolute best book on explaining the doctrine of election and grace in an understandable way. Also available in audio teaching format from Ligonier Ministries.
Unlimited-Limited Atonement sermon by Mark Driscoll – Very good sermon explaining the issues
TULIP Sermon Series by John Piper – Dr. Piper gives explanation of the meaning of the five points of Calvinism
