Mark 2:17 (ESV)
Those who are well have no need of a physician, but those who are sick. I came not to call the righteous, but sinners.
Thinking over that last part, Jesus is essentially saying that in his coming to earth, there are some people he calls, and some whom he does not. In other words, some people Jesus saves, and others he does not.
The natural discrimination falls at “the righteous” and “sinners;” the sinners are saved and the righteous are not! However, we also know that all have sinned and fall short of the glory of God. If everyone is a sinner, wherefore art the distinction?
Clearly then, the distinction of whether one is ‘called’ by Jesus is made based not on whether you are righteous or a sinner, but whether you consider yourself a pretty decent person or whether you despise yourself and repent in dust and ashes. Sound melodramatic? This latter group have the presence of mind to say, “Jesus, without you I am lost, and cannot hope to stand before God, in His glory and holiness, and say that I have lived a good life worthy of God’s stature and of being in His presence evermore.
All these implications Jesus packed into 9 words: I came not to call the righteous, but sinners.
(Well, translated over to ESV, it’s 9 words; maybe even less in Aramaic or Greek or Hebrew.)
