Does not scripture testify that Jesus had no sin? So regardless of being tempted in the wilderness, He did not sin and therefore the temptations from the devil were not temptations to Him because He did not give in to them and sinned.I have already answered why Jesus is not God, in MULTIPLE posts.
As for God Who cannot die, it is prophesied that the Lord will return at the end of the great tribulation when the armies of the world marches unto Jerusalem and the Jews will see the Lord of Whom they had pierced & mourn.
Zechariah 12:9 And it shall come to pass in that day, that I will seek to destroy all the nations that come against Jerusalem. 10 And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.
His feet shall touch down on the Mount of Olives.
Zechariah 14:1Behold, the day of the Lord cometh, and thy spoil shall be divided in the midst of thee. 2 For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city. 3 Then shall the Lord go forth, and fight against those nations, as when he fought in the day of battle. 4 And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south. 5 And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the Lord my God shall come, and all the saints with thee.
And so heed His words here.
Revelation 1:17 And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last: 18 I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
If you cannot align these scriptures to your belief, then may the Lord help you prune your beliefs so you can bear more fruit in the knowledge of Him since you are not getting the whole picture when Jesus is God the Son.
