The teaching in scripture about salvation and implantation of new life is likened to seed in the ground. The parallel is the seed of the word of God. When it is implanted, it accurately translates into the life of the mature plant. The metaphor of growth represents the spiritual life evolves from implantation of the saving word to a mature organism described by all the words. In this sense, there are spiritually blessed words or cursed words.

 I do not think that cursing proportionally represents hateful words toward someone. But it is equally describing something that is created as pox  of disorder. All things are caused by the precise word of His mouth. Not only does God give life and design but He also sustains all necessary things. All things are created to bring God glory, ordered by His final word. God's design in the universe are reordered to be unified by His word.

 But man has gone astray. When he sinned, he began to oppose all that God said. The sole way of blessing for man is to order his life by the word of God. Gods eternal counsel has determined the beginning from the end in His governance over the earth. God has established His laws, curses, decrees, statutes, and promises to rule the earth with supreme justice and equity. He has performed this by acting according to His word that cannot be thwarted.

 A tree that bears fruit is the visible display of His perfect work of Christ. Christ is the perfect display of objective reality. The sensible reason that we are successful is God has meticulously designed creation to be unified. He orders all things for His glory. This is why realistically hoping in His word is blessing oneself. It is vicariously experiencing the confident assurance that God's word is settled. In experiencing the harmonious unity of God's word as we hope for future success we discover our gifts by bearing much fruit. We communicate all of the praise to God for His considerable success in this world. God works in our humble lives by His word that cannot be thwarted.
