The kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost. Romans 14:17. RRe 313.1
It is the privilege of every Christian to enjoy the deep movings of the Spirit of God. A sweet, heavenly peace will pervade the mind, and you will love to meditate upon God and Heaven. You will feast upon the glorious promises of His Word.—Testimonies for the Church 1:159. RRe 313.2
When the Spirit of God controls mind and heart, the converted soul breaks forth into a new song; for he realizes that in his experience the promise of God has been fulfilled, that his transgression has been forgiven, his sin covered. He has exercised repentance toward God for the violation of the divine law, and faith toward Christ, who died for man’s justification. “Being justified by faith,” he has “peace with God through our Lord Jesus Christ.”—The Acts of the Apostles, 476. RRe 313.3
There is peace in believing, and joy in the Holy Ghost. Believing brings peace, and trusting in God brings joy. Believe, believe! my soul says, Believe. Rest in God. He is able to keep that which you have committed to His trust. He will bring you off more than conqueror through Him who hath loved you.—Testimonies for the Church 2:319. RRe 313.4
