I. What constitutes a sinner?

1. A sinner is, essentially, a moral agent. So much he must be, whatever else he may or may not be. He must have free will, in the sense of being able to originate his own activities. He must be the responsible author of his own acts, in such a sense that he is not compelled irresistibly to act one way or another, otherwise than according to his own free choice.

He must also have intellect, so that he can understand his own relations and apprehend his moral responsibilities. An idiot, lacking this element of constitutional character, is not a moral agent and can not be a sinner.

He must also have sensibility, so that he can be moved to action—so that there can be inducement to voluntary activity, and also a capacity to appropriate the motives for right or wrong action.

These are the essential elements of mind necessary to constitute a moral agent. Yet these are not all the facts which develop themselves in a sinner.

2. He is a selfish moral agent devoted to his own interests, making himself his own supreme end of action. He looks on his own things, not on the things of others. His own interests, not the interests of others, are his chief concern.

Thus every sinner is a moral agent, acting under this law of selfishness, having free will and all the powers of a moral agent, but making self the great end of all his action. This is a sinner.

3. We have here the true idea of sin. It is in an important sense, error. A sinner is one that “erreth.” “He that converteth a sinner from the error of his ways.” It is not a mere mistake, for mistakes are made through ignorance or incapacity. Nor is it a mere defect of constitution, attributable to its author. But it is an “error in his ways.” It is missing the mark in his voluntary course of conduct. It is a voluntary divergence from the line of duty. It is not an innocent mistake, but a reckless yielding to impulse. It involves a wrong end—a bad intention—a being influenced by appetite or passion, in opposition to reason and conscience. It is an attempt to secure some present gratification at the expense of resisting convictions of duty. This is most emphatically missing the mark.
