Dan Cruver has a gift for finding great gospel-centred material. Here'a couple he's spotted. You need to read them. Full of practical help to stay cross-centred... cruzcentrica.
The Centrality of the Gospel (Tim Keller) PDF
Gospel-Driven Sanctification PDF
And... my favourite little book on this vital issue:
CJ Mahaney - The Cross Centred Life
Until we see that Christian life isn't about "performance" (Bridges), or "plate spinning" (Mahaney) but actually about the application of the gospel to all of life we will never truly live.
