A short and concise view from a confessional and reformed baptist perspective. This primer is not an in-depth treatment at all, a 50 or so page primer, and it knows it. This is a benefit as the authors use their short work to explain the simple difference between trusting oneself and trusting in Christ alone by faith for salvation as well as how the same truth applies to our sanctification. We often view the gospel as the key to the house, yet think we need new or different things to navigate the house; God saves us through faith in the gospel, and we now live as His children by faith in those same promises. I recommend for someone who may be struggling with their assurance, to point them extra nos, or outside of themselves to Jesus, the true and faithful Son who unashamedly calls us His brothers. We are adopted by God, trust in Him, not yourself, He will assure you of your salvation.
