Based on the writings of Ellen White, prayer is essential for a number of reasons, primarily centered on it being the source of spiritual strength and the direct line of communication with God.
Here are the key reasons why we should pray:
*   **It is the Source of Spiritual Strength and Power:** Prayer is described as the "breath of the soul" and the "secret of spiritual power." Neglecting it leads to a loss of spiritual vitality and vigor.
    *   "Prayer is the breath of the soul. It is the secret of spiritual power. No other means of grace can be substituted, and the health of the soul be preserved." (
GW 254.4)
    *   "Remember that prayer is the source of your strength." (
7T 243.3)
*   **It Provides Defense Against Temptation:** Prayer is a necessary defense against the temptations of the enemy. Neglecting prayer leaves one vulnerable to sin.
    *   "The darkness of the evil one encloses those who neglect to pray. The whispered temptations of the enemy entice them to sin; and it is all because they do not make use of the privileges that God has given them in the divine appointment of prayer." (
SC 94.2)
*   **It Connects Us with God:** Prayer is direct communion with God, who is the source of all wisdom, peace, and happiness.
    *   "Prayer is communion with God, the Fountain of wisdom, the Source of strength, and peace, and happiness." (
7T 42.3)
*   **It Prepares Us for Daily Duties:** The strength gained through prayer helps prepare individuals for the challenges of daily life and keeps their spirit in peace.
    *   "The strength acquired in prayer to God, united with individual effort in training the mind to thoughtfulness and care-taking, prepares the person for daily duties and keeps the spirit in peace under all circumstances, however trying." (
4T 459.2)
*   **It Unlocks Heaven's Resources:** Prayer is presented as the key that gives believers access to the infinite resources of God.
    *   "Why should the sons and daughters of God be reluctant to pray, when prayer is the key in the hand of faith to unlock heaven's storehouse, where are treasured the boundless resources of Omnipotence?" (
SC 94.2)
*   **It is a Necessity for a Christian Life:** Due to the constant temptations and trials we face, prayer is not just a privilege but a necessity to be kept by God's power.
    *   "The temptations to which we are daily exposed make prayer a necessity. In order that we may be kept by the power of God through faith, the desires of the mind should be continually ascending in silent prayer for help, for light, for strength, for knowledge." (
4T 459.2)
