31 And to the angel of the assembly in Sardis write: These things saith he that has the seven Spirits of God, and the seven stars: I know thy works, that thou hast a name that thou livest, and art dead. 2 Be watchful, and strengthen the things that remain, which are about to die, for I have not found thy works complete before my God. 3 Remember therefore how thou hast received and heard, and keep [it] and repent. If therefore thou shalt not watch, I will come [upon thee] as a thief, and thou shalt not know at what hour I shall come upon thee. 4 But thou hast a few names in Sardis which have not defiled their garments, and they shall walk with me in white, because they are worthy. 5 He that overcomes, he shall be clothed in white garments, and I will not blot his name out of the book of life, and will confess his name before my Father and before his angels. 6 He that has an ear, let him hear what the Spirit says to the assemblies.

(Read Revelation 3:1-6)
The Lord Jesus is He that hath the Holy Spirit with all his powers, graces, and operations. Hypocrisy, and lamentable decay in religion, are sins charged upon Sardis, by One who knew that church well, and all her works. Outward things appeared well to men, but there was only the form of godliness, not the power; a name to live, not a principle of life. There was great deadness in their souls, and in their services; numbers were wholly hypocrites, others were in a disordered and lifeless state. Our Lord called upon them to be watchful against their enemies, and to be active and earnest in their duties; and to endeavour, in dependence on the grace of the Holy Spirit, to revive and strengthen the faith and spiritual affections of those yet alive to God, though in a declining state. Whenever we are off our watch, we lose ground. Thy works are hollow and empty; prayers are not filled up with holy desires, alms-deeds not filled up with true charity, sabbaths not filled up with suitable devotion of soul to God. There are not inward affections suitable to outward acts and expressions; when the spirit is wanting, the form cannot long remain. In seeking a revival in our own souls, or the souls of others, it is needful to compare what we profess with the manner in which we go on, that we may be humbled and quickened to hold fast that which remains. Christ enforces his counsel with a dreadful threatening if it should be despised. Yet our blessed Lord does not leave this sinful people without some encouragement. He makes honourable mention of the faithful remnant in Sardis, he makes a gracious promise to them. He that overcometh shall be clothed in white raiment; the purity of grace shall be rewarded with the perfect purity of glory. Christ has his book of life, a register of all who shall inherit eternal life; the book of remembrance of all who live to God, and keep up the life and power of godliness in evil times. Christ will bring forward this book of life, and show the names of the faithful, before God, and all the angels, at the great day.
