The Feast of Passover: had to do with “Peace with God”
The Feast of Unleavened bread and Feast of First Fruits: had to do with the “Peace of God”
The Feast of The Feast of Pentecost: has to do with the “Power of God”
The Feast of Pentecost is the 4th step that the believer must take towards the “Rest of God” which is typified by the Feast of Tabernacles.
Hebrews 4:9-11 There remains, then, a Sabbath-rest for the people of God; for anyone who enters God’s rest also rests from their works, just as God did from his. Let us, therefore, make every effort to enter that rest, so that no one will perish by following their example of disobedience.
