Ok, Matt. 7:2 I understand...
Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye? 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? 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. - Matt. 7:1-5 (Emphasis mine)
This seems pretty straight forward: if you judge someone, be ready to be judged using the same measure (e.g. if you're harsh, expect a harsh judgment). What I don't understand is a similar remark in Mark 4:24:
If any man have ears to hear, let him hear. And he said unto them, Take heed what ye hear: with what measure ye mete, it shall be measured to you: and unto you that hear shall more be given. For he that hath, to him shall be given: and he that hath not, from him shall be taken even that which he hath. - Mark 4:23-25 (Emphasis mine)
I don't really understand what this means in that context. Any thoughts?
