“The day of the Lord so comes as a thief in the night”1 Thessalonians 5:2; 2 Peter 3:10
Thieves do not forewarn their intended victims because they know that if they do they can expect a reception that would prevent their objective. In the unlikely circumstance they did warn the intended victim and the warning went unheeded they might still be successful.
The Day of the Lord – Jesus’ Second Coming – is presented in the Bible as coming like a thief. That is, His coming will not be expected by mankind. It will be a surprise to most, but not all. Paul writes, “But you, brethren, are not in darkness, so that this Day should overtake you as a thief” (1 Thessalonians 5:4). At this point I believe Paul is directly addressing believing Jews in the Tribulation period that culminates in Jesus Christ’s return but it certainly has application to believers today.
Unlike an earthly thief, the Lord has given clues in the Bible as to the timing of His coming (e.g. Matthew 24:32-35). No exact time is given or even suggested but conditions in the world at that time are described and, while some have always been observed the confluence and intensity of all descriptions can be observed now.
Paul (1 Thessalonians 4:15) and Peter (2 Peter 3:11f) believed Christ’s coming could have been in their lifetime so how much more us today? Peter goes on to say that this prospect should affect our daily lives as we “look for new heavens and a new earth in which righteousness dwells” (2 Peter 3:13). This will affect how we live.
Jesus (Matthew 24:43), Paul and Peter all attest that Jesus’ Second Coming will be unexpected by the general population but a few will be prepared (cf. Matthew 25:1-13). The difference is that some hear the warning and believe it. The problem in the world is that we have not heeded the Father’s admonition in Matthew 17:5, “This is My beloved Son in whom I am well pleased. Hear Him!” This is also a problem for the church as Jesus tells us in each of His letters to the seven churches recorded in Revelation 2 & 3, “He who has an ear, let him hear what the Spirit says to the churches.” We don’t hear God speaking because we are not listening. We are not listening because we do not believe God has spoken. Only Jesus can cause the spiritually deaf to hear (Mark 7:31-37). Come to Him!
