When you accept Jesus Christ as your Lord and God, from that Day on you have His Holy Spirit dwelling in you. 

His job, with your co-operation, is to make you learn the truths of the Word of God, the Bible, and live according to it.

The Word, in summary, teaches us to love the Lord and to love the neighbour as ourselves. To the extent we are doing this we are said to be bearing fruit, if we are not, we are seen as barren fields!

All those who have truly repented from their sinful and wicked life bear fruit!

"Therefore bear fruits worthy of repentance" [Matt.3:8]

Because all the fruit we bear, is the work of the Spirit of Christ, the Holy Spirit, the Lord said,

"I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing." [John 15:5]

As Christians, we are to acknowledge daily that all the good things we do to others and all the truths we share with others, are received from the Lord, through His Holy Spirit!

This is how we offer up ourselves to the Lord as grain offerings!

"I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service. 2 And do not be conformed to this world, but be transformed by the renewing of your mind..." [Rom.12:1,2]

In this spiritual sense, the Lord is our food and drink, and slowly and surely, we are being changed to be more and more like Him every day! 

This will continue until the Last Day of this Age, when all those who have been "feasting" on the Lord will be changed into immortals, right down to their flesh and bones, and then ascend up into heaven to forever be with the Lord in His heavenly Kingdom!

Now you can understand what the Lord meant when He said,

"Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day." [John 6:54]

The Feast of Harvest is another name; for Pentecost, which correctly falls on the 27th/28th of July 2014.

The 27th/28th of July 2014, I believe, is the Last Day of this Age! 

We feast spiritually on Christ Himself! 

He is our food and drink, when we are continually doing good according to the truths of His Word. 

All those who are doing this are going to be harvested up into heaven on the correct Day of Pentecost!

They're going to be received up into heaven as "new grain offerings", for on that Day, we're going to receive our new bodies!

"To those who seek glory, honor and immortality by perseverance in doing good, he will pay back eternal life. But to those who are self-seeking, who disobey the truth and obey evil, he will pay back wrath and anger. Yes, he will pay back misery and anguish to every human being who does evil, to the Jew first, then to the Gentile; but glory and honor and shalom to everyone who keeps doing what is good, to the Jew first, then to the Gentile." [Rom.7-10][Complete Jewish Bible]
