Two resources I think every Christian should own and be reading regularly:
1. A Gospel Primer for Christians: Learning to See the Glories of God's Love by Milton Vincent
2. The Cross Centered Life by C.J. Mahaney
It's so important for us to daily reflect on the Gospel and how that should change our lives. I therefore propose Logos take these two very small books and make them available for us all on the platform of choice for studying God's Word :)
