This book is as relevant today as when it was first published in 1629. Our busyness and activism so easily degenerate into a hypocrisy in which we keep up all the appearance of holiness without the heart of it. Christians even use Christ as a package to pass on to others, instead of enjoying him first and foremost as their own Savior. But true reformation must begin in the heart, with love for Christ. And that can only come when the free grace of God in Christ Jesus is preached.
