When I lived in Dallas in 2012 and 2013, I went to the Village Church where Matt Chandler preaches. Chandler has been through battles with brain cancer and has a great biblical perspective on the purpose of life and where to find joy. I came across this youtube video last week and was reminded how gifted by God this man is:
“The thing about Jesus Christ that I want us to get across this whole semester is that joy, immense joy and pleasure and fullness, will only be found when we stop compartmentalizing Jesus Christ and we allow Him to be center in all things . . . No man can worship God if he has an elevated opinion of himself or his own ability because he will not boast in the cross, he’ll boast in himself.”
Hope this is helpful for you!
