25 If we live by the Spirit, let us also walk by the Spirit. (ESV)
The two most important things in our Christian journey are the life of faith and the walk of faith. The person who grasps this is not far from being a master in experimental [experiential] theology, for they are vital points to a Christian. You will never find true faith unaccompanied by true godliness; on the other hand, you will never discover a truly holy life that does not have at its root a living faith relying upon the righteousness of Christ.
Woe to those who seek the one without the other! There are some who cultivate faith and forget holiness; these may be very high in orthodoxy, but they shall be very deep in condemnation, for they hold the truth in unrighteousness! There are others who have strained after a holy life but have denied the faith, like the Pharisees of old, of whom the Master said they were “whitewashed tombs.”1 We must have faith, for this is the foundation; we must have holiness of life, for this is the superstructure.
What use is the mere foundation of a building to a man on the day of tempest? Can he hide himself in it? He needs a house to cover him as well as a foundation for that house. Even so we need the superstructure of spiritual life if we want comfort in the day of doubt. But do not seek a holy life without faith, for that would be to erect a house that can provide no permanent shelter because it has no foundation on a rock. Let faith and life be put together, and like the two supports of an archway, they will make our devotion endure. Like light and heat streaming from the same sun, they are full of blessing. Like the two pillars of the temple, they are for glory and for beauty. They are two streams from the fountain of grace, two lamps lit with holy fire, two olive trees watered by heavenly care.
Lord, give us today life internally, and it will reveal itself externally to Your glory.
