''Now about the times and seasons, brothers, we do not need to write to you. For you are fully aware that the day of the Lord will come like a thief in the night.'' 1 Thessalonians 5:2

Every day, is a potential day. No man knoweth the hour except our Father in heaven. ( Matthew 24:36 )

Θλίβω ( thlibo ) and Θλίψης ( thlipsis ) literally mean - to induce sorrow and -sorrow.
