Matthew 24: 36-51
Therefore, stay awake, for you do not know on what day your Lord is coming. (Matthew 24:42 ESV)
We don't know the exact year, day, or hour that Jesus will return. I do believe that authentic believers will have an innate sense about his approach, but the details are beyond us. It is something we do not know, and cannot know until the moment in which we experience it.
Jesus compared it to being watchful over a house in danger of robbery. If you knew your house was going to be robbed you would take all kinds of extra precautions. And if you knew the exact moment in the night when the robber was going to approach you would be ready.
Christ will return, and when he does he wants to embrace a ready church. He is looking for a people that are awake, alert, and watching. So, stay awake.
