Jesus returns at the end of the "Great Tribulation" which is when the Millennium commences. NB The exact date and time is unknown. There is no answer to your question at the moment, all that we have to go on are what is called The Signs of the Times. God will tell Christ when the time is right for the millenium to commence. It is no good us speculating, what we need is to be ready and worthy to recieve Him when He does come. That we are in the last few seconds of earth time as we know it is certain. Just make sure that you are ready to recieve your Christ when He does come. Who knows, it may be in your lifetime.
