15 Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ, 16 from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.
Other Resources for Growth
Below are some of the other resources Joshua Olson mentioned in this exhortation.
Gospel Fluency: Speaking the Truths of Jesus into the Everyday Stuff of Life by Jeff Vanderstelt.
These Gospel Fluency resources go through the various aspect of the gospel and how they apply to everyday life. They provide a very helpful guide to be able to apply the gospel to your life and the lives of your friends.
Christ Is the End of the Law, by John Calvin
This is probably the best summary of the entire story of the scriptures. It points to Jesus as the both the sum and center of the story of redemption. The gospel is here explained in such beautiful and poetic fashion that it cannot help but lead a believer to worship!
How Does Sanctification Work? by David Powlison
This book provides a great description of how the gospel applies to life and changes us.
Redemption Accomplished and Applied by John Murray
Murry's book is yet another great resource on the nature and application of the gospel.
