While in His pre-resurrection, human nature, Jesus knew that He had limitations regarding the full manifestation of His God-nature (Jn. 17:1-5). He knew also that He had a glory which was suspended because of His mission on earth. However, with all the limitations, Jesus still walked on the sea; rebuked the wind, cast out demons and they all obeyed Him. But more significantly, Jesus gave orders to His disciples, “go ye therefore, do miracles, heal and also cast out devils” (Lk. 9:1-6; 10:1).
The argument then is this, If in the days of His limited earthly ministry, the devils were subject unto His disciples by His name, what shall be the case now that He has conquered all, and all the power in heaven and on earth have been given to Him? Invariably, His post-resurrection order/ command when He has got the name above all names, and all power in heaven and earth have been given to Him, must be much greater (Phil. 2:10-12)
