Rev 3:1 And unto the angel of the church in Sardis write; These things saith he that hath the seven Spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead.
Rev 3:2 Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.
Rev 3:3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
Rev 3:4 Thou hast a few names even in Sardis which have not defiled their garments; and they shall walk with me in white: for they are worthy.
Not everyone in that Church was doing wrong,but there was some people that were doing right,for our salvation does not depend on the Church we go to that has hypocrites,for how can you find a Church perfect that does not have any hypocrites,unless there is only 2 people that attend that Church.
A hypocrite is not one that sins,and repents,and keeps moving forward,but a hypocrite is one that holds unto the wrongdoing,and think they are alright,or do not care and say,I will get rid of it in the future,but will not let it go until they decide to get rid of it when they are good and ready.
These people that were wrong in Sardis had a habit of wrongdoing,and not laboring as they should,possibly being lazy.
2Ti 2:20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.
2Ti 2:21 If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
God said there will be some hypocrites in the Church,but it is still a great house,for it the Church speaks truth,and there is hypocrites,it is still a great house,and many there that also do right.
The ones who were to dishonor were not prepared unto every good work,like Sardis where Jesus did not find their works perfect before God,which are what the Spirit would have us do,for no works of the flesh matter.
But if our Church speaks truth,the hypocrites do not affect our salvation,for it is still a great house.
