That is true no man knows the day Jesus will come back,not even the angels.
1But of the times and the seasons, brethren, ye have no need that I write unto you.
2For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6Therefore let us not sleep, as do others; but let us watch and be sober(1 Thessalonians 5:1-6).
These are the scriptures that they use to say that the children of the light will be ready and the day of the Lord will not overtake them as a thief in the night,but we have to see what this really means,and to rightly divide the word of truth.
1But of the times and the seasons, brethren, ye have no need that I write unto you.
2For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
These 2 scriptures prove that the saints do not know the day of the Lord,for Paul said that he did not need to write unto the saints concerning the times and the seasons concerning Jesus' return,because that day comes as a thief in the night,and Paul does not know himself.Paul said there is no need for us to know the times and seasons concerning Jesus' return,for Jesus said that no man can know,and that He will come as a thief in the night,so there is no need for Paul to write concerning that.
3For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4But ye, brethren, are not in darkness, that that day should overtake you as a thief.
They believe that since it says that the saints are not in darkness,that that day should overtake them like a thief,that it is talking about the day of the Lord,but this is not talking of the day of the Lord,but of the time when they say peace and safety,that will fool the world into believing that the world coming together is the solution to solve the world's problems,but the saints will not be fooled by it,and know that only by Jesus can man prosper.
10Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
11Behold, I come quickly: hold that fast which thou hast, that no man take thy crown(Revelation 3:10-11).
I believe that the letters to the 7 Churches is symbolic of how the Church age will go up until Jesus returns,for there is only one temptation that can tempt all the people of the world,and that is when they say peace and safety,for it is follow the one world government and religious system,which the beast system has power over all the world,and Jesus said He will not even allow the saints to be tempted with the idea that the one world government and religious system is of God.
Paul is saying that the saints will not be caught as a thief when they shall say peace and safety to think that it is the best for the world and of God,and Jesus will not even let them be tempted to believe it is of God,for it will lead to the beast system,which the saints know is not of God,where the world will think it is of God.
Like the false prophet will do lying wonders that will appear to be so real,that it would deceive the very elect,if it were possible,but it is not possible to deceive the elect for they are the elect.
Since Paul said that he has no need to write unto us about the time of Jesus' return,for we cannot know for it comes as a thief in the night,then Paul would not write that when they say peace and safety that that day shall not overcome them like a thief,as having any reference to the day of the Lord,but meaning they will not fall victim to the beginning of the one world government and religious system that will lead to the beast system.
Paul is giving us a little hint to let us know that the day of the Lord is near,when they say peace and safety for the world,but has no need to tell of the times and seasons of Jesus' return,which means the plan of God concerning that day,for it comes as a thief in the night,which Paul does not know,the angels do not know,and Jesus said no man knows,and only the Father knows.
When Paul says that he has no need to write to us about the times and seasons concerning Jesus' return,it means the plan of God concerning a certain time frame,but the events happen on one day,like when the Jews asked Jesus if He was going to restore the kingdom on earth back to the Jews at that time,and He said it is not for them to know the times and seasons,but only the Father,and God will restore the kingdom to them on one certain day,in the millennial reign of Christ,and it is the day of the Lord,not the days of the Lord.
