For a person to believe/trust/act upon the fact that Jesus Christ of Nazareth died for our sins and rose from the grave and is alive today, that person must be drawn by the Father (soul stuff) to Jesus Christ of Nazareth (because we can approach the Father through the earthen vessel of the Father, which example shows us what a real Son of God is, cause He's real). If someone asks me if Jesus Christ of Nazareth is the Son of God, the answer is yes. If someone asks me if Jesus Christ is God, the answer is yes. Both are true is a very common conclusion in matters pertaining to God. All with no beginning are God Himself, that's how powerful He is.
If we tell someone that they really need to trust in Jesus Christ of Nazareth (I have found that many people understand the word trust better than believe), then we have taken on the task of showing them how we trust in God if that person chooses to trust in Jesus Christ of Nazareth. There will be questions, but the person does not need to have active knowledge that Jesus is God in order for them to be found trusting in God. Knowing Jesus more and more each day is something that happens automatically when we truly do want to.
If this is truly just a question of Jesus Christ of Nazareth being God or not, then I have these reminders (with scriptural support if needed, but I think we all know that these reminders are from scripture).
Exo_20:3 Thou shalt have no other gods before me.
I could give scripture again to remind us of The Captain of the Host of the Lord, and the priest forever after the order of Melchisidec (that's two witnesses), but I'll give another witness from Jesus Christ of Nazareth (which is the third in this reminder).
Don't ignore the verily, verily part
Joh 8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
So if we're really just trying to figure out if scripture supports that Jesus Christ of Nazareth is God, then I've given three witnesses. If someone disagrees concerning those witnesses, then I would ask what they think the name is of the person worshiped in the other two appearances mentioned?
We know that soul and spirit are not the same, but are connected. We know we have earthen vessels. Is it so hard to understand that there's parts to a walnut, but it's still one walnut? (there's better examples I know, but that one is hard to not understand). Jesus Christ of Nazareth is the Holy Spirit of the Right Hand of the Father, or I could say that Jesus Christ of Nazareth is what we are going to be (which we don't know exactly, but it includes an earthen vessel), only He has no beginning, and there is no measure with God, but we have a measure.
1Jn_3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
We want to nourish people up when they decide to trust in Jesus, and if we cannot explain with scripture what the Son of God is, then we cannot give that person one of the greatest confidence boosters ever, which is knowing that Jesus Christ of Nazareth is God.
Luk 20:41 And he said unto them, How say they that Christ is David's son?
Luk 20:42 And David himself saith in the book of Psalms, The LORD said unto my Lord, Sit thou on my right hand,
Luk 20:43 Till I make thine enemies thy footstool.
Luk 20:44 David therefore calleth him Lord, how is he then his son?
So maybe we should take a baby step and agree yes or no concerning who the two men were?
Heb 7:1 For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;
Heb 7:2 To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;
Heb 7:3 Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.
Jos 5:13 And it came to pass, when Joshua was by Jericho, that he lifted up his eyes and looked, and, behold, there stood a man over against him with his sword drawn in his hand: and Joshua went unto him, and said unto him, Art thou for us, or for our adversaries?
Jos 5:14 And he said, Nay; but as captain of the host of the LORD am I now come. And Joshua fell on his face to the earth, and did worship, and said unto him, What saith my lord unto his servant?
Jos 5:15 And the captain of the LORD'S host said unto Joshua, Loose thy shoe from off thy foot; for the place whereon thou standest is holy. And Joshua did so.
