Q. 136. {4} Is this likeness in the body or in the soul? 
A. This likeness is chiefly in the soul.

Q. 137. {5} How is the soul like to God? 
A. The soul is like to God because it is a spirit that will never die,
and has understanding and free will.

Q. 138.  Is every invisible thing a spirit?  A. Every spirit is invisible—­which means can not be seen; but every invisible thing is not a spirit.  The wind is invisible, and it is not a spirit.

Q. 139.  Has a spirit any other quality? 
A. A spirit is also indivisible; that is, it can not be divided into
parts, as we divide material things.

Q. 140.  What do the words “will never die” mean?  A. By the words “will never die” we mean that the soul, when once created, will never cease to exist, whatever be its condition in the next world.  Hence we say the soul is immortal or gifted with immortality.

Q. 141.  Why then do we say a soul is dead while in a state of mortal sin?  A. We say a soul is dead while in a state of mortal sin, because in that state it is as helpless as a dead body, and can merit nothing for itself.

Q. 142.  What does our “understanding” mean?  A. Our “understanding” means the “gift of reason,” by which man is distinguished from all other animals, and by which he is enabled to think and thus acquire knowledge and regulate his actions.

Q. 143.  Can we learn all truths by our reason alone?  A. We can not learn all truths by our reason alone, for some truths are beyond the power of our reason and must be taught to us by God.

Q. 144.  What do we call the truths God teaches us?  A. Taken together, we call the truths God teaches us revelation, and we call the manner by which He teaches them also revelation.

Q. 145.  What is “Free Will”?  A.  “Free Will” is that gift of God by which we are enabled to choose between one thing and another; and to do good or evil in spite of reward or punishment.

Q. 146.  Have brute animals “understanding” and “free will”?  A. Brute animals have not “understanding” and “free will.”  They have not “understanding” because they never change their habits or better their condition.  They have not “free will” because they never show it in their actions.

Q. 147.  What gift in animals supplies the place of reason?  A. In animals the gift of “instinct” supplies the place of reason in guiding their actions.

Q. 148.  What is instinct?  A.  “Instinct” is a gift by which all animals are impelled to follow the laws and habits that God has given to their nature.

Q. 149.  Have men as well as brutes “instinct”?  A. Men have “instinct,” and they show it when placed in sudden danger, when they have not time to use their reason.  A falling man instantly grasps for something to support him.

Q. 150. {6} Why did God make you?  A. God made me to know Him, to love Him, and to serve Him in this world, and to be happy with Him forever in the next.
