Truth is, in the end the result is the same: we are unable to come up to God's level of righteousness and holiness and need a Savior. "Missing the mark" sounds a little more innocuous than rebellion, but whether you miss the strait gate, avoid it on purpose, or just get confused and follow the crowd down the broad path, you end up in the same place.To clear something up here, sin does not literally mean "miss the mark". One word in Greek that is translated as sin in most Bibles actually means "miss the mark", the other word means wrongdoing. Both are translated as "sin" for convenience, and to avoid doctrinarian. I tend to distinguish them as willful sin vs. a mistake or error, but many others also make no distinction whatsoever. Different denominations have different perspectives on where the relevance lies.
