The number 7 in the scriptures is the number of completion or perfection.
Many times it is associated with the Church.
John wrote to 7 churches in Revelation. There are 21 chapters in John’s Gospel and there are 7 chapters in John’s epistles.
Paul wrote to 7 churches in his epistles. There are 70 chapters (7 X 10) from Romans through 1 Thessalonians which is Pentecost to the Rapture. The last chapter in 1 Thessalonians (chapter 5) has 28 verses in it (7 X 4). As a side note 2 Thessalonians which prophetically lines up as a witness to the Gentiles in the 1st half of the tribulation has 3 chapters for 3 years and ends with verse 18 (6+6+6)
Enoch was the seventh generation from Adam and is a type of the raptured church (he never died but was raptured). He is mentioned as the seventh from Adam in Jude 14 (2 X 7).
There are 7 “kingdom of God is like” parables; 4 in Mark and 3 in Luke.
The 7th commandment is thou shalt not commit adultery because the church is the bride of Christ and marriage between a man and a woman is a physical witness to the spiritual relationship between Christ and His church.
During the tribulation period, the number 7 is associated with the final judgements of God before the return of Jesus Christ. There are 7 seals, 7 trumpets, and 7 vials.
The tribulation period is 7 years in length.
Some other sevens contained in the book of Revelation are:
the seven stars, the seven candlesticks, the seven Spirits of God representing the sevenfold ministry of the Holy Spirit (see Isaiah 11:2), the word “book” used 28 times (7 X 4), the word “prophecy is used 7 times, and the word “blessed” is used 7 times.
The completion of the harvest (the gleanings) is described in Revelation 7 and in Revelation 14, the 144000 have been raptured.
God completed His creation on the 7th day by resting and the 7th period of 1000 years is the period of rest for the earth and the nation of Israel where Christ will reign from Jerusalem.
This completes the study of the number 7 in the Bible.
