Evangelical doctrines and evangelical experience

In reading John Owen, I have gained two particular insights into evangelicalism:

1. The evangel, the good news, is not merely the means by which we receive life and enter the family of God; it is that by which we live every breath. Inasmuch as we portray it merely as the means of escape from hell, or the starting point of the Christian life, we betray its true power as the news that never ceases to be good and never ceases to be our salvation.
2. It is possible to have evangelical doctrine without evangelical experience. One can have orthodox doctrinal knowledge of Christ, "but the sight of his glory does not consist in that" (190).

Owen put it this way:

It is a great evidence of the power of unbelief, when we can satisfy ourselves without an experience in our own hearts of the great things, in this kind of joy, peace, consolation, assurance, that are promised in the Gospels. For how can it be supposed that we do indeed believe the promises of things future, namely, of heaven, immortality, and glory, the faith of which is the foundation of all religion, when we do not believe the promises of the present reward in these spiritual privileges? And how shall we be thought to believe them, when we do not endeavor after an experience of the things themselves in our own souls, but are even contented without them? (Owen, John. "The Glory of Christ." Glasgow: Christian Heritage. 2004. p198)

Evangelical experience is just as important as evangelical doctrine. For how can we believe these great truths without seeking an experience of the things themselves in our own souls?
