This week marks the biblical festival of Shavuot, also known as the Festival of Weeks and Pentecost. It is the day God gave His people the Torah through Moses and it is the same day God gave his Spirit to His people through Jesus/Yeshua. It is very much a festival believers should know about.
I believe the 7 biblical festivals are prophetic and teach us much about the first and second coming of Messiah.
So here are a few links to learn and study a bit more about one of them, Shavuot.
Ask the Holy Spirit to reveal more about it to you as you study the scriptures.
