Jesus is the Lord Jehovah that had appeared to Abraham, Isaac, & Jacob in the O.T.
Jesus Is Jehovah
Read it in context;
Matthew 4:8 Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; 9 And saith unto him, All these things will I give thee, if thou wilt fall down and worship me. 10 Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.
Jesus said those words to rebuke the devil that he is to worship Him instead.
Even the unclean spirits acknowledged Him as God for why they had worshipped Him.
Mark 5:2 And when he was come out of the ship, immediately there met him out of the tombs a man with an unclean spirit, 3 Who had his dwelling among the tombs; and no man could bind him, no, not with chains: 4 Because that he had been often bound with fetters and chains, and the chains had been plucked asunder by him, and the fetters broken in pieces: neither could any man tame him. 5 And always, night and day, he was in the mountains, and in the tombs, crying, and cutting himself with stones.
6 But when he saw Jesus afar off, he ran and worshipped him, 7 And cried with a loud voice, and said, What have I to do with thee, Jesus,
thou Son of the most high God? I adjure thee by God, that thou torment me not.
Hence the Son of God is God of the Three Witnesses within the One God.
Note the switch now of the first commandment from the Old Covenant to the New Covenant.
1 John 3:23
And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment. 24 And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
This is so for those who have trouble loving Gd with all of their heart, soul, mind, & strength because no matter how much the spirit is willing, the flesh is weak therefore what is impossible with man, is possible with God. By believing in Jesus Christ is how we have hope in loving God with our heart, mind, souls, & His strength.
In context again;
1 Corinthians 8:5 For though there be that are called gods, whether in heaven or in earth,
(as there be gods many, and lords many,) 6 But to us there is but
one God, the Father, of whom are all things, and we in him; and
one Lord Jesus Christ, by whom are all things, and we by him.
How about asking Jesus at that throne of grace why you are praying to Him when we are only to pray to God? And while you are at it, ask Him why one God and one Lord means the same thing as referring to deity?
Ask Him why denying Him as God is the same thing as denying the Father as God at the same time?
1 John 2:20 But ye have an unction from the Holy One, and ye know all things. 21 I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth. 22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. 23 Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also. 24 Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father. 25 And this is the promise that he hath promised us, even eternal life.
John 10:27 My sheep hear my voice, and I know them, and they follow me: 28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. 29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand. 30 I and my Father are one.
31 Then the Jews took up stones again to stone him. 32 Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me? 33 The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.
Yes, Jesus is God. That is why He was crucified. It wasn't for leaving the toilet seat up or an overdue library book or unpaid parking tickets.
