Jesus could speak as God,or as a man,while on earth.
Joh 20:27 Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing.
Joh 20:28 And Thomas answered and said unto him, My Lord and my God.
Joh 20:29 Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.
Jesus did not rebuke Thomas when He called Him,Lord and God,for Thomas was acknowledging Jesus according to His diety.
Mat 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
The man that called Jesus,good Master,was acknowledging Jesus according to His humanity,and Jesus gave glory to God,and said,I am doing good,because God is causing Me to do good.
Mat 8:2 And, behold, there came a leper and worshipped him, saying, Lord, if thou wilt, thou canst make me clean.
Mat 8:3 And Jesus put forth his hand, and touched him, saying, I will; be thou clean. And immediately his leprosy was cleansed.
Mat 8:5 And when Jesus was entered into Capernaum, there came unto him a centurion, beseeching him,
Mat 8:6 And saying, Lord, my servant lieth at home sick of the palsy, grievously tormented.
Mat 8:7 And Jesus saith unto him, I will come and heal him.
Mat 14:28 And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water.
Mat 20:30 And, behold, two blind men sitting by the way side, when they heard that Jesus passed by, cried out, saying, Have mercy on us, O Lord, thou Son of David.
Mat 20:31 And the multitude rebuked them, because they should hold their peace: but they cried the more, saying, Have mercy on us, O Lord, thou Son of David.
Mat 20:32 And Jesus stood still, and called them, and said, What will ye that I shall do unto you?
Mat 20:33 They say unto him, Lord, that our eyes may be opened.
Mat 20:34 So Jesus had compassion on them, and touched their eyes: and immediately their eyes received sight, and they followed him.
Many people called Jesus,Lord,and Jesus did not rebuke them accepting them calling Him,Lord,which is the same as Jesus saying He is God,for Lord could only apply to God.If Jesus accepted being called Lord,it is the same as if He is saying He is God.
Mat 11:25 At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
Luk 4:12 And Jesus answering said unto him, It is said, Thou shalt not tempt the Lord thy God.
Lord is a title only given to God,for no human can be Lord.
Luk 7:13 And when the Lord saw her, he had compassion on her, and said unto her, Weep not.
Luk 7:31 And the Lord said, Whereunto then shall I liken the men of this generation? and to what are they like?
Here it is attributing Jesus as God.
Mat 12:8 For the Son of man is Lord even of the sabbath day.
Mat 21:3 And if any man say ought unto you, ye shall say, The Lord hath need of them; and straightway he will send them.
Luk 6:46 And why call ye me, Lord, Lord, and do not the things which I say?
Joh 13:13 Ye call me Master and Lord: and ye say well; for so I am.
Joh 13:14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet.
Jesus called Himself Lord,which can only be applied to God,which means Jesus is saying He is God from His own mouth.
And Jesus forgave sins which only God can forgive sins,and said before Abraham was,I am,and said He will not leave the saints comfortless,but come to them.
This is from the perspective of Jesus on earth that He did claim to be God,for He accepted being called Lord,and called Himself Lord.
And there are many scriptures that testify Jesus is God.God said He would come as the Savior,the Son shall be called the mighty God,He will have no beginning,He is God manifest in the flesh,He dwells in the light whom no man can approach,and no person has ever seen Jesus,and no person will ever see Jesus,according to His invisible Spirit,and He is the Almighty.
Jesus did claim to be God while on earth,when He called Himself Lord,which it a title that can only apply to God,and no human.
The Bible identifies Jesus as Lord to show that He is God in a visible manifestation on earth,and the ruler,and authority,of mankind,and when it refers to Jesus as Lord,it is the same as if it is referring to Jesus as God,in case some may say why does it not say God,but Lord,but to say Lord,is the same as to say God.
Jesus' lifestyle on earth testifes He is God,and it cannot be denied.
