1 Thess 5:1-4 But concerning the times and the seasons, brethren, you have no need that I should write to you. For you yourselves know perfectly that the day of the Lord so comes as a thief in the night. For when they say, “Peace and safety!” then sudden destruction comes upon them, as labor pains upon a pregnant woman. And they shall not escape. But you, brethren, are not in darkness, so that this Day should overtake you as a thief.

While Jesus says no one knows the day and hour of His return, the Bible also tells believers we can know the time and seasons, perhaps the day although not the day and hour together.
Jesus will return like a thief in the night.
Our church was robbed seven times and we never caught them in the act because they all came at night.
However, we did take measures by installing an alarm system and security cameras.
Now they don’t bother with us.
I’m not sure drug dealers make their deals in the parking lot anymore because of the security cameras.
Even though thieves are still around the area they just don’t try to break in anymore.
Likewise, believers are not in darkness so that day catches us unaware.
We positively know Jesus will return.
And in my study of the scripture, I believe He returns on Yom Teruah, also known as the Feast of Trumpets.
Therefore I claim to know the day but I certainly do not know the hour.
Whether I am right or wrong, Jesus is returning so it is high time we prepare for His return and what better way than spreading the gospel message to those that need to hear it.
