Thoughts Form Character.--As a man "thinketh in his heart, so is he" (Proverbs 23:7). Many thoughts make up the unwritten history of a single day, and these thoughts have much to do with the formation of character. Our thoughts are to be strictly guarded, for one impure thought makes a deep impression on the soul. An evil thought leaves an evil impress on the mind. If the thoughts are pure and holy, the man is better for having cherished them. By them the spiritual pulse is quickened and the power for doing good is increased. And as one drop of rain prepares the way for another in moistening the earth, so one good thought prepares the way for another.--YI, Jan 17, 1901.
Power to Choose Thought Topics.--It is within the power of everyone to choose the topics that shall occupy the thoughts and shape the character.--Ed 127 (1903).
Requires Personal Effort.--No one but yourself can control your thoughts. In the struggle to reach the highest standard, success or failure will depend much upon the character and the manner in which the thoughts are disciplined. If the thoughts are well girded, as God directs they shall be each day, they will be upon those subjects that will help us to greater devotion. If the thoughts are right, then as a result the words will be right; the actions will be of that character to bring gladness and comfort and rest to souls.--Lt 33, 1886.
Thoughts to Be Trained.--The thoughts must be trained. Gird up the loins of the mind that it shall work in the right direction and after the order of well-formed plans; then every step is one in advance, and no effort or time is lost in following vague ideas and random plans. We must consider the aim and object of life, and ever keep worthy purposes in view. Every day the thoughts should be trained and kept to the point as the compass to the pole. Everyone should have his aims and purposes, and then make every thought and action of that character to accomplish that which he purposes. The thoughts must be controlled. There must be a fixedness of purpose to carry out that which you shall undertake.--Lt 33, 1886.
Training the Thoughts.--The actual discipline of life is made up of the little things. The training of the thoughts is essential.--MS 76, 1900.
The training of the heart, the control of the thoughts, in cooperation with the Holy Spirit, will give control of the words. This is true wisdom, and will ensure quietness of mind, contentment and peace. There will be joy in the contemplation of the riches of the grace of God.--Lt 10, 1894. 2MCP 655-656
If you go the wrong way—to the right or to the left—you will hear a voice behind you saying, "This is the right way. You should go this way." Isaiah 30:21 (New Century Version)
