Okay. Some quick biblical facts here.
A. Jesus did grow in wisdom (Luke 2:52).
B. Jesus operated by the power of the Father (John 14:10-11), and the Holy Spirit (Matthew 12:28).
Jesus had power as God:
(During His Earthly ministry):
#1. Jesus said He has power to raise the dead to life just as the Father had power to raise the dead (John 5:21).
#2. Hebrews 1:3 talks about how Christ held all things together by the word of His power when He purged us of our sins.
#3. Jesus said, He would raise up this Temple (His body) three days later (John 2:19).
#4. Jesus had the power to forgive sins and give eternal life (Mark 2:7) (Luke 7:44-50) (John 14:6).
#5 Jesus had power to take away the sins of the entire world (John 1:29).
#6. Jesus Christ said wherever two or three are gathered in my name, there I am among them (Matthew 18:20). This was said to the people he was around and not to just us today.
#7. Jesus knew men's thoughts (Matthew 9:4) (Matthew 12:25) (Mark 2:8) (Luke 5:22) (Luke 6:8) (Luke 9:47) (Luke 24:38).
#8. Jesus knew about the lives of others (John 2:24) (John 4:17-18) (John 4:29) (John 6:64).
Conclusion:
On point A., Jesus most likely suppressed His divine attribute of Omniscience, and gained access to a part of it when needed.
On point B., it is not a contradiction for Jesus to have power and also operate by the power of the Father, and the Spirit, too. Please look at the verses on Jesus having power during His earthly ministry. It is clear that Jesus always had power. For logic dictates that in order to be God, you have to have the power of God. Jesus (or the Living Word) never stopped being God. He may have suppressed His divine attributes or power, but He did not ever lose them.
