Did God the Father commanded Christ to the cross or did He go of His own free will? Well let's look at what the bible says!
Matt.26:
38 Then he said to them, "My soul is very sorrowful, even to death; remain here, and watch with me."
39 And going a little farther he fell on his face and prayed, saying, "My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as you will."
Matt.26:
53 Do you think that I cannot appeal to my Father, and he will at once send me more than twelve legions of angels?
54 But how then should the Scriptures be fulfilled, that it must be so?"
John 12:
27 "Now is my soul troubled. And what shall I say? 'Father, save me from this hour'? But for this purpose I have come to this hour.
28 Father, glorify your name." Then a voice came from heaven: "I have glorified it, and I will glorify it again."
29 The crowd that stood there and heard it said that it had thundered. Others said, "An angel has spoken to him."
30 Jesus answered, "This voice has come for your sake, not mine.
31 Now is the judgment of this world; now will the ruler of this world be cast out.
32 And I, when I am lifted up from the earth, will draw all people to myself."
Heb.5:
7 In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence.
8 Although he was a son, he learned obedience through what he suffered.
9 And being made perfect, he became the source of eternal salvation to all who obey him,
10 being designated by God a high priest after the order of Melchizedek.
John 5:
30 "I can do nothing on my own. As I hear, I judge, and my judgment is just, because I seek not my own will but the will of him who sent me.
31 If I alone bear witness about myself, my testimony is not true.
32 There is another who bears witness about me, and I know that the testimony that he bears about me is true.
33 You sent to John, and he has borne witness to the truth.
34 Not that the testimony that I receive is from man, but I say these things so that you may be saved.
35 He was a burning and shining lamp, and you were willing to rejoice for a while in his light.
36 But the testimony that I have is greater than that of John. For the works that the Father has given me to accomplish, the very works that I am doing, bear witness about me that the Father has sent me.
37 And the Father who sent me has himself borne witness about me. His voice you have never heard, his form you have never seen,
38 and you do not have his word abiding in you, for you do not believe the one whom he has sent.
39 You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me,
40 yet you refuse to come to me that you may have life.
41 I do not receive glory from people.
42 But I know that you do not have the love of God within you.
43 I have come in my Father's name, and you do not receive me. If another comes in his own name, you will receive him.
44 How can you believe, when you receive glory from one another and do not seek the glory that comes from the only God?
45 Do not think that I will accuse you to the Father. There is one who accuses you: Moses, on whom you have set your hope.
46 For if you believed Moses, you would believe me; for he wrote of me.
47 But if you do not believe his writings, how will you believe my words?"
Phil.2:
8 And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
9 Therefore God has highly exalted him and bestowed on him the name that is above every name,
10 so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,
11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Just as Christ had a choice and chose obedience to the Father, so do you! You can bow to your Lord God or you can live in rebellion and receive the eternal consequence!
Heb.9:
27 And just as it is appointed for man to die once, and after that comes judgment,
28 so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him.
Romans 3:
23 for all have sinned and fall short of the glory of God,
24 and are justified by his grace as a gift, through the redemption that is in Christ Jesus,
25 whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins.
26 It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus.
