Revelation 2:25

23 And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.

24 But unto you I say, and unto the rest in Thyatira, as many as have not this doctrine, and which have not known the depths of Satan, as they speak; I will put upon you none other burden.

But that which ye have already hold fast till I come.

26 And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations:

27 And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father.

Do read the surrounding verses too, because the context often says more than a single verse.
