Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer. Psalm 19:14. OHC 113.1
The thoughts must be pure, the meditations of the heart must be clean, if the words of the mouth are to be words acceptable to Heaven, and helpful to your associates.38The Review and Herald, June 12, 1888. OHC 113.2
The natural, selfish mind, if left to follow out its own evil desires, will act without high motives, without reference to the glory of God or the benefit of mankind. The thoughts will be evil, and only evil, continually.... The Spirit of God produces a new life in the soul, bringing the thoughts and desires into obedience to the will of Christ.... OHC 113.3
The youth should begin early to cultivate correct habits of thought. We should discipline the mind to think in a healthful channel, and not permit it to dwell upon things that are evil.... As God works upon the heart by His Holy Spirit, man must cooperate with Him.... OHC 113.4
We should meditate upon the Scriptures, thinking soberly and candidly upon the things that pertain to our eternal salvation. The infinite mercy and love of Jesus, the sacrifice made in our behalf, call for most serious and solemn reflection. We should dwell upon the character of our dear Redeemer and Intercessor. We should seek to comprehend the meaning of the plan of salvation. We should meditate upon the mission of Him who came to save His people from their sins. By constantly contemplating heavenly themes, our faith and love will grow stronger. Our prayers will be more and more acceptable to God, because they will be more and more mixed with faith and love. They will be more intelligent and fervent. There will be more constant confidence in Jesus, and you will have a daily, living experience in the willingness and power of Christ to save unto the uttermost all that come unto God by Him.... OHC 113.5
There will be a hungering and thirsting of soul to be made like Him whom we adore. The more our thoughts are upon Christ, the more we shall speak of Him to others, and represent Him to the world.39The Review and Herald, June 12, 1888. OHC 113.6
