Yesterday, in part two of our series on the Holy Spirit, we focused on why the indwelling of the Holy Spirit leads to humility and holiness (listen here). I mentioned some resources in my sermon and you can check them out here.
The Holy Spirit by John Owen (Puritan Paperback, updated language, small book)
Holiness Demanded by C.H. Spurgeon (free PDF of a sermon on Heb. 12:14)
