If you’re looking for a thorough study of assurance, or if you’re teaching or preaching through 1 John, you’ll want to get your hands on Chris Bass’s new book, That You May Know: Assurance of Salvation in 1 John, which is volume 5 in the NAC Studies in Bible and Theology.
Chris and his family are doing important work planting a church in the Boston area, so if you’re looking for a church in that part of the country you should check them out.
I would encourage you to read this book and pray for Redeemer Fellowship Church.
May the Lord build his church!
