Was Jesus Impeccable as a man walking this earth for 33 years ? Yes or no
Was Jesus omniscient, omnipresent and omnipotent as a man walking this earth for 33 years ? Yes or no
Jesus Christ was totally led of the Spirit of God while he was on the earth in the same way that all born again saints of God will be in the eternal state. The Spirit of God led Jesus Christ in everything he did or said because Jesus Christ willed it so. So, the answer to the second question is "no." Here is what the scriptures says about him while he was in the weak flesh.
Phi 2:5 Let this mind be in you, which was also in Christ Jesus:
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
10 That at the name of Jesus every knee should bow, of [things] in heaven, and [things] in earth, and [things] under the earth;
11 And [that] every tongue should confess that Jesus Christ [is] Lord, to the glory of God the Father.
Here is what Jesus Christ said about himself.
John 12:44 Jesus cried and said, He that believeth on me, believeth not on me, but on him that sent me.
45 And he that seeth me seeth him that sent me.
46 I am come a light into the world, that whosoever believeth on me should not abide in darkness.
47 And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world.
48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
49 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
50 And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
Stop and consider these words above. Jesus Christ spoke the words that God gave him to speak. It says this in V 49. This is the reason he says what he does in V 44. How can this be? There is only one way this can be true isf I have given you the right answer to question #2. It is because God has given him the Holy Spirit without measure (Jn 3:34) and he indwells him in his fullness. While Jesus Christ has limited himself in character to live as a man, so as to accomplish redemption for the world, the Spirit that lives in him is also in the Father, and according to 1 Cor 2, searches the mind of the Father. In his fullness and dwelling in Jesus Christ, being omnipresent and not constrained by time and space, Jesus can know the mind of God immediately through and by the Spirit. Not only so, the Spirit empowers our Lord to accomplish the will of God in his body. The one and only time that Jesus acted alone was the time on the cross when God the Father and God the Spirit forsook him , and he died. That is the meaning of death. Separation. It was the meaning of his eventual physical death when his human soul and his human body were separated and his soul went to paradise where the thief who was crucified with him and had repented had already gone, and his body was placed in a tomb.
How is the person of Jesus different than born again sinners today. The answer is simple. While Jesus Christ was the son of God at his conception through the virgin, none of us sinners can say that. Jesus Christ is the only begotten of the Father. However, those who have believed the gospel of Christ by putting their trust in him and the Father also have received the Spirit as the gift of God to indwell our mortal bodies. But, there is a difference between us and Jesus Christ when he lived on the earth. While he was given the Spirit without measure, we are given the "earnest" of the Spirit, a down payment, as it were, on the finished transaction of our redemption. We are commanded to be filled with the Spirit only because in most cases we are not. When Christians endeavor to do things for God, such as my writing this explanation of the Christian faith, we should be led of the Spirit and filled with the Spirit, so that which is done will glorify God. Jesus said he did always those things that please the father.
The Spirit of God can be "quenched" in us.
The Spirit of God can be "grieved" by us.
Neither of these things were ever true of Jesus Christ.
I can add much scripture, in context, to strengthen my points above but I will let this be my post for now and see if you are able to think outside the Calvinist box. It is important that you do.
2 Cor 1:21 Now he which stablisheth us with you in Christ, and hath anointed us, [is] God;
22 Who hath also sealed us, and given the earnest of the Spirit in our hearts.
2Co 5:5 Now he that hath wrought us for the selfsame thing [is] God, who also hath given unto us the earnest of the Spirit.
13 In whom ye also [trusted], after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
14 Which is the earnest of our inheritance until the redemption of the purchased possession (he is speaking of the redemption of the body, it's glorification), unto the praise of his glory.
Please take time to read this and ponder it.
Rom 8:15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
23 And not only [they], but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, [to wit], the redemption of our body.
Eph 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
1Th 5:19 Quench not the Spirit.
