Men are here on earth to become the image and likeness of Jesus.

Rom 8:29 For those whom He (God) foreknew He also predestined to be conformed to the image of His Son, in order that he might be the first-born among many brethren.
Lk 6:40 A disciple is not above his teacher, but every one when he is fully taught will be like his teacher.
1 Cor 15:49 Just as we have borne the image of the man of dust (adam), we shall also bear the image of the Man of heaven (Jesus). 
Gn 1:26 Then God said, “Let us make man in our image, after our likeness; and let them have dominion over the fish of the sea, and over the birds of the air, and over the cattle, and over all the earth, and over every creeping thing that creeps upon the earth.” 
1:27 So God created man in his own image, in the image of God he created him; male and female he created them.
