My son had a spelling list and he had to determine which ones were spelt incorrectly. I told him that it is easier to know if they were wrong if he knew the right ones well, had read them often, and was familiar with what they were supposed to look like.
Christian, it is the same way with sin. Often we do not even recognize things as sin because we have no reference in our hearts to compare to. Like a spelling word, instead of consulting Webster’s Dictionary, too often we consult an urban dictionary or use the latest acronym and allow our own opinions or the opinions of man to be our reference point without ever bothering to check it against the ultimate standard.
Sometimes we are aware that there is something wrong, but we are not sure what exactly it is. It is only by constant exposure to the written Word of God, and unceasing prayer for Christ to reveal truth by His Spirit to our blind eyes that we can ever know with any confidence what sin lurks in our hearts, minds and lives. So let us not rely on our own view of things, or consult the opinions of surrounding culture, but let us go to the source of all truth knowing that it is only that reference that matters.
“But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work. “(2 Timothy 3: 14-17)
