Sin also carries on its war by entangling the affections and drawing them into an alliance against the mind. Grace may be enthroned in the mind, but if sin controls the affections, it has seized a fort from which it will continually assault the soul. Hence, as we shall see, mortification is chiefly directed to take place upon the affections.
John OwenThere is not a day but sin foils or is foiled, prevails or is prevailed upon. It will always be so while we live in this world. Sin will not spare for one day. There is no safety but in a constant warfare for those who desire deliverance from sin's perplexing rebellion.
John OwenA natural man hath no such thing as free-will at all, if you take it for a power of doing that which is good and well-pleasing unto God in things spiritual.
John OwenGreat winds and storms help fruit-bearing trees. So also do corruptions and temptations help the fruitfulness of grace and holiness. The storm loosens the earth round its roots so the tree is able to get its roots deeper into the earth, where it receives fresh supplies of nourishment. But only much later will it be seen to bring forth better fruit. So corruptions and temptations develop the roots of humility, self-abasement and mourning in a deeper search for that grace by which holiness grows strong. But only later will there be visible fruits of increased holiness.
