John Calvin, Golden Booklet of the True Christian Life:
The gospel is not a doctrine of the tongue, but of life.
It cannot be grasped by reason and memory only, but is fully understood when it possesses the whole soul and penetrates to the inner recesses of the heart.
Let nominal Christians cease from insulting God by boasting themselves to be what they are not, and let them show themselves disciples not unworthy of Christ, their Master.…
Our religion will be unprofitable if it does not change our heart, pervade our manners, and transform us into new creatures.
Words of Grace
