God's Rhythm of Harvest:Shavuot / Pentecost

Jesus told us He fulfills every jot and tittle of Scripture. This is certainly seen in the 3 feasts of the Lord, that align with the agricultural harvests. And Jesus uses these to teach Kingdom principles.
Using these principles, Ruth explores the comparison between Passover and Shavuot, Mt Sinai and the day of Pentecost, the Book of Ruth and the Tower of Babel.
So many connections and interconnections and comparisons.
They all confirm:
(1) Align with and obey the Lord, and blessings come. OR
(2) Disobey and break covenant and there is trouble.
