You are taking Jesus out of context (as far too many "Christians" are wont to do):
"For ye have the poor with you always, and whensoever ye will ye may do them good: but me ye have not always." - Mark 14:7 (emphasis mine)
The emphasis is on the fact that his end was coming, not a justification for not trying to help all of the poor.
"1 Judge not, that ye be not judged.
2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
3 And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?
4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?
5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye." - Matthew 7:1-5
One does not even have to be a "believer" to understand what is really meant here.
