Is Jesus God? How he described himself:
Jesus therefore said to them, "Truly, truly, I say to you, it is not Moses who has given you the bread out of heaven, but it is My Father who gives you the true bread out of heaven. For the bread of God is that which comes down out of heaven, and gives life to the world." They said therefore to Him, "Lord, evermore give us this bread." Jesus said to them, "I am the bread of life; he who comes to Me shall not hunger, and he who believes in Me shall never thirst." (John 6:32-35)
Again therefore Jesus spoke to them, saying, "I am the light of the world; he who follows Me shall not walk in the darkness, but shall have the light of life." The Pharisees therefore said to Him, "You are bearing witness of Yourself; Your witness is not true." Jesus answered and said to them, "Even if I bear witness of Myself, My witness is true; for I know where I came from, and where I am going; but you do not know where I come from, or where I am going." (John 8:12-14)
Jesus therefore said to them again, "Truly, truly, I say to you, I am the door of the sheep. All who came before Me are thieves and robbers, but the sheep did not hear them. I am the door; if anyone enters through Me, he shall be saved, and shall go in and out, and find pasture. The thief comes only to steal, and kill, and destroy; I came that they might have life, and might have it abundantly. I am the good shepherd; the good shepherd lays down His life for the sheep." (John 10:7-11)
Martha therefore said to Jesus, "Lord, if You had been here, my brother would not have died. Even now I know that whatever You ask of God, God will give You." Jesus said to her, "Your brother shall rise again." Martha said to Him, "I know that he will rise again in the resurrection on the last day." Jesus said to her, "I am the resurrection and the life; he who believes in Me shall live even if he dies, and everyone who lives and believes in Me shall never die. Do you believe this?" She said to Him, "Yes, Lord; I have believed that You are the Christ, the Son of God, even He who comes into the world." (John 11:21-27)
Is Jesus God? What he said he was sent here to do:
But Jesus called them to Himself, and said, "You know that the rulers of the Gentiles lord it over them, and their great men exercise authority over them. It is not so among you, but whoever wishes to become great among you shall be your servant, and whoever wishes to be first among you shall be your slave; just as the Son of Man did not come to be served, but to serve, and to give His life a ransom for many." (Matthew 20:25-28)
For He was teaching His disciples and telling them, "The Son of Man is to be delivered into the hands of men, and they will kill Him; and when He has been killed, He will rise three days later." But they did not understand this statement, and they were afraid to ask Him. (Mark 9:31-32)
"For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have eternal life. For God did not send the Son into the world to judge the world, but that the world should be saved through Him. He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God." (John 3:16-18)
"All that the Father gives Me shall come to Me, and the one who comes to Me I will certainly not cast out. For I have come down from heaven, not to do My own will, but the will of Him who sent Me. And this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. For this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day." (John 6:37-40)
