I always enjoyed reading and listening to Tim Keller. He had a way of taking an abundance of knowledge and distilling it for everyday use. Instead of letting knowledge puff up he would lead it to the heart where it could do some good.
He passed away this year after a struggle with cancer but even his funeral shows the marks of his thoughtful approach to faith.
I would encourage you to download the bulletin of the service from Redeemer’s website. He left some notes for us on why he picked the hymns he did and why they sang them in that order.
This is a great illustration of why song selection and liturgy (order of service) matter. With the right songs and order even a funeral can be turned into a triumphant declaration that Christ has conquered death.
