Broadly speaking, I learned to recognize sin as the refusal to live up to the enlightenment we possess: to know the right order of values and deliberately to choose the lower ones: to know that, however much these values may differ with different people at different stages of spiritual growth, for one's self there must be no compromise with that which one knows to be the lower value.
Paul, using the examples of differing opinions about food and days among the believers in Rome, teaches that Christians should not despise or judge others. He does not advise them to find a happy medium between the contending opinions or to average the two extremes in a compromise. On the contrary, he admonished them that "every one be fully convinced in his own mind" (Rom. 14:5), because God is able to make both stand, as both of them are serving the Lord in obedience to their individual convictions of His will. . . . Each of us has to find personally what is the will of God for his own life, and let all others meet their responsibility to do the same. . . . For God, by giving different commands to many, and putting them together according to His plan, shall accomplish ultimately His complete will.
Compromise makes a good umbrella, but a poor roof; it is a temporary expedient, often wise in party politics, almost sure to be unwise in statesmanship.
Recently a large group of 'problem' children were given the assignment of writing essays on the difficulties they had with their parents. The papers they turned in were misspelled but lively, listing a number of rather predicable faults - gushing, nagging, refusing affection, and so on. But oddly enough the quality most children felt their parents lacked was truthfulness. None of us, of course, likes to think of himself as a liar. In important things we make it a point to be scrupulously honest. But if we examine our daily lives closely we may find dozens of examples of small compromises, trivial evasions. These seemingly unimportant deceits should be guarded against, since they can all too easily become a part of the fabric of our existence, influencing our relationships with others. An unflagging desire for truth in every aspect of our behavior does much to provide that sense of security for which all people yearn.
