Revelation 2:25; 3:10-11
25 ‘Nevertheless what you have, hold fast until I come.
10 ‘Because you have kept the word of My perseverance, I also will keep you from the hour of testing, that hour which is about to come upon the whole world, to test those who dwell upon the earth. 11 ‘I am coming quickly; hold fast what you have, in order that no one take your crown.
In these two references, which pertain to the church in Thyatira and Philadelphia, the coming of Christ is mentioned. And in both references they were to “hold fast” until He comes.
In the Thyatira church, though they had good deeds (2:19), they were permitting a woman to teach and lead many people into sin (to worship idols and to commit sexual sins, 2:20). Thus the Lord was telling those who had not followed her teaching to hold on tightly to the truth they had until He comes.
The church in Philadelphia also had good deeds, but there were some who were infiltrating the church who were not truly Jewish believers; they were of “the synagogue of Satan” (3:9). This hypocrisy, along with various trails, it seems, was causing many of the true believers to be severely tested. For this reason, the Lord encouraged them, like the Thyatirans, to hold fast to the truth they had until He comes. And for this church, He promised them: “Because you have kept the word of My perseverance, I also will keep you from the hour of testing, that hour which is about to come upon the whole world, to test those who dwell upon the earth” 3:10).
This “hour of testing” I think refers to the 7-year Tribulation; for it will come upon the whole world. And though the promise here that He would keep them from this hour is made specifically to this church, this does not mean that He will not keep all believers from it. Yes, He will keep us out of it—He will resurrect and rapture all the church before that time of wrath.
Therefore, these references to His coming—that we should “hold fast” until He comes—refers to the first phase of His second coming. So let us hold on tightly to all that we know is true until He comes to take us to that wonderful place that He has been preparing for us (Jn. 14:1-3).
