Simon Peter, a servant and an apostle of Jesus Christ, to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ…According as His divine power hath given unto us all things that pertain unto life and godliness… – 2 Peter 1:1,3

There be some who cultivate faith and forget holiness; these may be very high in orthodoxy, but they shall be very deep in damnation, in that day when God shall condemn those who hold the truth in unrighteousness, and make the doctrine of Christ to pander to their lusts. There are others who have strained after holiness of life, but have denied the faith; these are comparable unto the Pharisees of old, of whom the Master said, they were “whitewashed sepulchres;” they were fair to look upon externally, but inwardly, because the living faith was not there, they were full of dead men’s bones and all manner of uncleanness. Ye must have faith, for this is the foundation; ye must have holiness of life, for this is the superstructure. Of what avail is the mere foundation of a building to a man in the day of tempest? Can he hide himself among sunken stones and concrete? He wants a house to cover him, as well as a foundation upon which that house might have been built; even so we need the superstructure of spiritual life if we would have comfort in the day of doubt. But seek not a holy life without faith, for that would be to erect a house which can afford no permanent shelter, because it has no foundation on a rock-a house which must come down with a tremendous crash in the day when the rain descends, and the floods come, and the winds blow, and beat upon it. Let faith and life be put together, and, like the two abutments of an arch, they shall make your piety strong. Like the horses of Pharaoh’s chariot, they pull together gloriously. Like light and heat streaming from the same sun, they are alike 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; two stars carried in Jesus’ hand. The Lord grant that we may have both of these to perfection, that His name may be praised.~ C.H. Spurgeon
