At every stage of its existence a plant may be perfect.
Indeed, without perfection there cannot be perfect growth. 
We are “complete in Him,” yet we are to “grow in grace.”
We are to be… Colossians 1:9...filled with the knowledge of His will in all wisdom and spiritual understanding,–and yet are to be: 10 Fruitful in every good work, and increasing in the knowledge of God.
Jesus in the temple at the age of twelve knew God as His Father. His knowledge was as absolutely sure as it ever was; yet: Luke 2:52 He increased in wisdom and stature, and in favor with God and man.
Real growth in the knowledge of God can take place only when there is absolute knowledge of Him; otherwise our growth would be crooked."
