So, is this possible?  Can each of us start out as mortal, flawed, fallen human beings and finish 'as he is'?  Apparently so, because that is the message of the restored gospel of Jesus Christ.  Everything about the gospel teaches us that we can become like our Heavenly Parents, but never on our own!  The role of our Savior facilitates that process according to our cooperation with Him.  He is the source of that change.  So it is understandable that one of the ways this goal is described is as 'the pure love of Christ', denoting our journey to 'come unto' him and allow him to change us to be like him with him in us, and us in him.  So D & C 4 heralds the restoration of this marvelous work and in just seven verses describes how it can work for us.  Sure it is a great missionary section, but also invaluable for personal guidance.  And note the last verse:  "Ask, and ye shall receive; knock, and it shall be opened unto you."  Why is the "seek and ye shall find" from the Sermon on the Mount in both the New Testament and 3 Nephi missing.  Perhaps it is because with the restoration of the gospel through the Prophet Joseph Smith we have already found 'Him' and now work to establish communion with him that culminates in a perfect union described as "Charity".
