Gerhardt's meditation on the Desire for Eternal Life emphasizes the contrast between the fleeting nature of earthly life and the eternal joy and fulfillment promised in the life to come. The themes of preparation, spiritual maturity, and the hope found in Christ are central, as is the idea that the beauty we experience here is just a glimpse of the greater beauty awaiting believers in eternity. ---- In this meditation, Johann Gerhardt emphasizes the transient nature of this earthly life and encourages the soul to focus on the eternal life that is to come. This promised eternal life to come is a place of perpetual youth, without the infirmities of old age. Life is no longer followed by death, and joy is untainted by sorrow. The fleeting nature of earthly pleasures and the inevitability of death are contrasted with the eternal and unchangeable kingdom promised to believers.
This life now is a preparation for the life to come. Our current existence is likened to being in the womb, with our true selves only fully realized in eternity. Life on earth is not permanent. Despite knowing its temporary nature, spiritual maturity is gained and comes with accepting the limitations of this life.
The removal of the tree of life after the fall of Adam and Eve is a merciful act by God. It prevented mankind from entering eternal life in a fallen state. The hope and assurance of eternal life is only in Christ. This is where death no longer has power, and where everything we do is filled with eternal meaning.
Beauty and fulfillment are found in the new heavens and the new earth. This is where believers will shine like the sun in the kingdom of their Father. The enjoyment of beauty here is a foretaste of the even greater beauty to be experienced in eternity.
