Back of the question, how far may we be free from sin is the further problem, “What is sin?” and it is in answering this question that we may fall into a fundamental misconception which leaves us confused when reading the plain statements of Scripture. Many a supposed difference among Christians regarding freedom from sinning rests back in a difference in their definition of “sinning.” But this is far more serious than a mere difference in the definition of a word, which might be passed over as unimportant. For, as we shall see, if our use of the word “sinning” differs from that which God means by sin, there is sure to result a confusion which will affect our experience in the matter of deliverance from sin. There is substantial agreement that Christians should be, and may be, free from dishonesty, lying, stealing, jealousy, strife, bitterness, evil speaking, fornication, covetousness, and a thousand other sins that might be named. Also it is agreed that it is not for Christians to grow out of such sins, nor to get rid of them gradually, but to put them off as wholly inconsistent with the Christian walk. How complete is the list of such sins that a Christian may be free from just now? Or to put the question in another form, how much sin is it necessary for a Christian to have? “But,” some one asks, “is not everything that falls short of God’s absolute standard of perfection sin?” Our purpose in this study is intensely practical, and so it is not the intention to enter into a full discussion of theological terms. It may be suggested in passing that many who use such an expression as “God’s absolute standard of perfection,” would find great difficulty in explaining just what they mean. But we may here get at the problem as it presents itself in experience. All are agreed that there is no possibility of perfection of attainment in this body, meaning by such perfection an absence of all error or mistake in everything that is done. We may go further and say that by this standard of “perfection” every act falls short, and every moment of life is compassed with infirmity. If this kind of “falling short” is sin, then there can be full agreement that there is no such thing as freedom from sinning in this body. (It would not be entirely accurate to say, “if this imperfection is sin,” for “perfection,” like all words――and everything else human――is imperfect and relative and takes its meaning from the thought in the mind of the user.) Is such falling short sinning? Or to reduce the question to practical everyday experience, “Is every act of the Christian sinful, as well as every word and thought?”
