REST: Dormancy [rest] occupies a specific season in the natural growth cycle of plants. Dormancy is a period during which the plant may appear to be dead because there is no growth. It is a period of rest for the plant. Dormancy usually occurs right before a period of very rapid growth. In the natural world, God commanded times of rest for the land (Leviticus 25:5).
One of the purposes of the baptism of the Holy Spirit is to bring spiritual rest and refreshing. This spiritual refreshing results in rapid growth of the fruit of the Holy Spirit:
Let us fear, lest a promise being left us of entering into his rest, any of you would seem to come short of it.
There remaineth therefore a rest to the people of God. (Hebrews 4:1,9)
For with stammering lips and another tongue will He speak to this people.
To whom He said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing... (Isaiah 28:11-12)
DEATH: Every time you plant a seed to produce fruit, it does not come to life unless it dies first: Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit. (John 12:24)
Everytime you plant a seed, you sow something that does not come to life [germinating, springing up, and growing] unless it dies first. (I Corinthians 15:36) The Amplified Bible
Spiritual life depends on death to the things of the world. It requires death to sin, worldly desires, and pleasures. Death to the world results in the development of the fruit of Christ-likeness in your life.
