The Feasts of Israel
The most important aspect of the Feasts of Israel is that Jesus Christ fulfills them all during the early and latter rain.
"Therefore be patient, brethren, until the coming of the Lord. See how the farmer waits for the precious fruit of the earth, waiting patiently for it until it receives the early and latter rain. You also be patient. Establish your hearts, for the coming of the Lord is at hand (James 5:7,8, NKJV).
Jesus Christ fulfilled the feasts during the early rain by His death (Passover), His burial (unleavened bread), His resurrection (Firstfruits), and His outpouring of the Holy Spirit (Pentecost).
Since these first four feasts were precisely fulfilled, we are promised the latter rain with the Rapture of the Church (Trumpets), His Second Coming (Atonement), and His Millennial Kingdom (Tabernacles).
It is one thing to hear this teaching in types and shadows from the Scriptures (Leviticus 23), but it is even better to create a chart to help with greater spiritual understanding.
I pray these efforts will increase your knowledge and understanding of the Feasts of Israel, and that your faith will increase in Christ and His soon return.
