Most assuredly, I say to you, unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain. John 12.24
The grain of wheat symbolizes a servant; God the Father is the Sower and God the Son was His Firstfruit, the First grain of wheat. From that First grain came other grains (the servants).
But before a servant serves as the grain of wheat, he must first be born of water and the Spirit. It is not possible to serve God without first being born of God. Because, how can you serve Someone that is Unseen and Unknown? If this is impossible, imagine trying to figure out what is His Will? The only One that can reveal the Will of God is the Spirit of God.
Therefore, to serve Him, first the servant must be born of the Holy Spirit, following the example of the Lord Jesus who was begotten in the virgin Mary. Only then does the servant become the seed of God on Earth, following the example of the Lord Jesus.
The same way, the wheat grains generated and chosen by God the Spirit serve God the Son in this world and are considered by the Lord as servants.
If the servants do not die to themselves and to the world, how will they produce other grains?
Let’s take a look at the steps the Lord Jesus took here on Earth:
First, He was born of the Holy Spirit. (Matthew 1.18);
Second, He was baptized in water and the Holy Spirit (Matthew 3.16);
Third, He was led by the Holy Spirit into the wilderness (Matthew 4.1);
Fourth, He lived to do the will of His Father, because He was made Servant (John 6.38);
Fifth, He died and consummated the Work of Salvation, conquering death, the world and hell (Isaiah 53 and John 19.30);
Sixth, He sat down at the right hand of God the God (Hebrews 1.3, 12.2) and
Seventh, He sent His Spirit to guide His disciples (Acts 2.1-4).
Whoever wants to serve the Lord Jesus has to walk in these footsteps, because the only things that prepare real servants of God are deserts and trials.
