It is the Spirit alone that can mortify sin; he is promised to do it, and all other means without him are empty and vain. How shall he, then, mortify sin that has not the Spirit? A man may easier see without eyes, speak without a tongue, than truly mortify one sin without the Spirit.
John OwenWhatever vices and corruptions men see in the lives of their ministers will not be attributed to the depravity of their old nature which still abides in them, but to the gospel.
John OwenThe Scripture abounds in commands and cautions for our utmost diligence in our search and inquiry as to whether we are made partakers of Christ or not, or whether His Spirit dwells in us or not-which argue both the difficulty of attaining an assured confidence herein, as also the danger of our being mistaken, and yet the certainty of a good issue upon the diligent and regular use of means to that purpose.
