“For the word of God is quick, and powerful, and sharper than any two edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.” Hebrews 4:12.
As a man “thinketh in his heart, so is he.” 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.
The longest journey is performed by taking one step at a time. A succession of steps brings us to the end of the road. The longest chain is composed of separate links. If one of these links is faulty, the chain is worthless. Thus it is with character. A well-balanced character is formed by single acts well performed. One defect, cultivated instead of being overcome, makes the man imperfect, and closes against him the gate of the Holy City. He who enters heaven must have a character that is without spot or wrinkle or any such thing. Naught that defiled can ever enter there. In all the redeemed host not one defect will be seen. –Messages to Young People, p. 144.
