Moon

God created the moon as a marker of seasons, days and years (Gen 1:14-18). The Psalmist, when considering the vastness of the creator's heavenly handiwork, is astounded that God is concerned with us, insignificant humanity (Ps 8:3,4). Yet God’s instruction remains, don’t worship the sun, moon or stars (Deut 4:19)

The new moon in Bible times marked the beginning of a new month of the Hebrew lunar-based calendar.

An interesting fact about the full moon is that it appears bright and beautiful, but it does not produce its own light; it only reflects the sun's light. Without the sun, the moon is just a dark rock in space. Similarly, we were created to reflect His light and qualities in this world to point people to Jesus (Gen 1:27; Mt 5:15; Jn 1:4,5, 8:12).

During a lunar eclipse, the moon is sometimes called a blood moon because it appears reddish brown. The phenomenon is a result of sunlight scattering through Earth's atmosphere during an eclipse, which typically occurs one or two times per year.

Some people speculate this phenomenon signals the fulfilment of end-times prophecies where the Bible states, “The sun will be turned to darkness and the moon to blood before the coming of the great and dreadful day of the Lord…the whole moon turned blood red…” (Joel 2:30,31; Rev 6:12). These descriptions should not be taken as a technical statement, rather the sun’s light will be blocked, and the moon will have a reddish blood like blood appearance. This natural event may point to the Lord’s return at the end of time. Again, it could be a supernatural darkness, like the darkness during Jesus’ crucifixion (Mt 27:45). The sun and moon's appearance will change, no matter what causes it. Jesus indicated that such a phenomenon would occur at the end of the tribulation period shortly before He returns to Earth. “Immediately after the tribulation of those days, the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken. Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory” (Mt 24:29,30). This will take place after the rapture and tribulation.

A blue moon doesn’t appear to be blue, but is a term used to indicate when a second full moon occurs within the same calendar month. The moon's cycle is 29.5 days, slightly less than a calendar month, so on average, this event happens every two to three years.
