The difference in God's creation between man and his (God's) other creation is that God spoke and all other things come forth. For man, God first thought about him (Eph 1:4), then spoke about him (Gen 1:26) and finally made him (Gen 2:27). The purpose in the making of man was so that on earth (in the "seen" world) man would reveal the attributes of his Maker (who dwells in the "unseen" world - the spirit realm)!
