The Jewish New Year.
A time of repentance.
24Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation.
As Christians we are not under the old law. But we can still learn from the old ways.
Rosh HaShanah marks the beginning of ten days of repentance, and prayer.
Ten is an important number in the Bible. When reading this, the first thing I thought of was the ten virgins. Five were wise and had their oil, but five were foolish and didn't have enough oil. Perhaps this would be a good time to fill our lamps, our bodies, with the Holy Spirit, Seek the Lord with all that is in us. And repent.
Here is a sight that explains Rosh Hashanah.
Get quiet, listen hard, and see if you can hear the Trumpets.
