Matthew 21:32

For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye saw it, did not even repent yourselves afterward, that ye might believe him.

Thus, the prior entry of publicans and harlots was not due to any divine preference for their kind of sins, but was the result of their response, their hearing, believing, repenting, and being baptized. All the vaunted righteousness of the Pharisees could not save them while they were in rebellion against God's commands, nor can all the moral excellence of upright men today avail anything for them apart from faith and obedience of the Lord's commandments. By the same premise, all the sins of the publicans and harlots could not take away their hope as long as they heard and obeyed the Lord. Christ himself put it like this, "He that believeth and is baptized shall be saved, and he that believeth not shall be condemned" (Mark 16:15,16).
