I believe it will happen very soon. The word says that the anti christ will stand in a temple proclaiming to be christ. They are building a temple in Jerusalem right on top of where they believe the holy of holies was, it is being built next to the dome of the rock. They have already laid two corner stones. The Bible says that it will happen in Jerusalem, and it is not a coincidence that they are building a temple in Jerusalem right now. The word says in the last days, there will be teachers that people will gather up to tell them what their itching ears want to hear. These things are happening right now. There is not anyone in the modern churches that is teaching The Truth. If you think that your beliefs are right, you should test them with the word, to see if they are, or not, otherwise you are just following your own opinions rather than The Truth that saves. They are setting up a one world order, that will bring all the world religions together, and say that we must all love one another and get along for the sake of their peace. But it is not the peace that comes from God, but it is of the world. Christ said: "my kingdom is not of this world." Neither should ours be if we are Christians. "Come out from them, and be separate, be holy as I am holy says the Lord". They are trying to make this world a better place, but to no avail. Remember, they will be saying: "peace and safety, then destruction will suddenly come upon them". "Satan masquerades as an angel of light and his followers as teachers of righteousness". So we must walk by the Spirit, not by the flesh which cannot please God. If we walk by the Spirit God gives discernment to us, so that we can see the truth, from the counterfeit/false. These things are true. They are happening, and we must build ourselves up in the most holy faith, knowing time is short on this earth anyway, preach the gospel, save souls, and make disciples. This is the call for all believers. Stop just talking, because the kingdom of God is not about talk, but of Power from the Spirit of Christ through us.
1 Corinthians 4:19-20
19 But I will come to you very soon, if the Lord is willing, and then I will find out not only how these arrogant people are talking, but what power they have. 20 For the kingdom of God is not a matter of talk but of power.
1 Thessalonians 5:1-3
5 Now, brothers, about times and dates we do not need to write to you, 2 for you know very well that the day of the Lord will come like a thief in the night. 3 While people are saying, Peace and safety, destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
