God is father of all. God is the in-dweller of all. But there is a difference in the manifestation of God's power in everyone.
Though an ant and an elephant are children of God, and though God indwells in ant as well as in elephant, there is a difference in power between them. This concept of difference in power manifestation was frequently taught by Ramakrishna Paramahamsa.
Your science teacher who teaches Newton's law of motions is not equal to Newton. A priest who eloquently explains Bible is not equal to Jesus Christ. Leave alone knowledge. Even in expressing love, I am not equal to a 1 year old baby next doors.
