Very little written about Jesus except the NT.
Well, Jesus says, about the early scriptures,
"'You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me.'" (John 5:39)
There are things in the early scriptures which are understood to be prophesies about Jesus, for one example Psalm 22. Also, from how God handles things during early scripture history, we can get understanding about Jesus and how He is, including . . . though . . . how He judges. There is a lot about judging sin, in the early scriptures. This can show us that it is better to be with God. This is not "very little" to get, I would "think"
There is judgment (John 16:7-11) . . . not just smiley-face grace from God at a distance!
"God resists the proud," we have in James 4:7 and also in 1 peter 5:5.
Because our Father cares about us, He personally resists each of us while we are doing things in ego - - so we do not keep on in the direction where Satan has us going in ego (Ephesians 2:2). And then is when I can get upset and downcast and bent out of shape about not getting my own way. But my nasty and negative reacting can be a warning to me, that I am getting away from God; and then I can trust God to correct me and restore me into sweet and sensitive sharing with Him and submitting to . . . discovering . . .
how He rules me in His peace >
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
A lot of early scripture history is an object lesson about what can happen if people do things without Jesus. So, it is definitely about Jesus, in one way or another. God perfectly does His good to people, in the early scripture, and His judging is perfect; yet, without Jesus, even God gets "nowhere" with people. We need Jesus in us, as our "electromagnet" to attract us together with all that is God, or else our lives are like what happens to all those iron filings on paper over an electromagnet which is turned off.
With Jesus, things make sense, because Jesus in us is our light of love - - - so that we can see things the way love has us seeing and reacting and responding with compassion with hope.
Jesus in us is the living Word of God . . . the living and loving meaning of every scripture. And as I have offered, all the negative things of Bible history are object lessons, fair warnings. God knows how much He can do with a person who refuses to have His Son living in that person >
"without Me, you can do nothing" (in John 15:5).
Satan was in Heaven itself, but he was not satisfied with Heaven itself, even . . . though there were such perfect surroundings and all the loving in Heaven. So, Satan got thrown out > Luke 10:17-20. And, likewise, if judgment is in Heaven . . . plenty of people will go to Heaven for their day of judgment, yes, but will they stay there? Will they want to? Plenty of selfish people, in the Gospels, could not stand Jesus!! So, yes ones boast they are going to "Heaven", but if they are selfish, how much will they enjoy our Groom? Ones may go to Heaven, but will they stay there? If we have lived selfishly, we "might" not enjoy being in Heaven and with Jesus.
"If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me." (in Luke 9:23)
I understand He means our cross of all-loving love which has us also glad to forgive and do loving good to people who do not deserve to have us bear burdens for them and suffer for them, like how Jesus on the cross did for us >
His example is required of us >
"And walk in love, as Christ also has loved us and given Himself for us, an offering and a sacrifice to God for a sweet-smelling aroma." (Ephesians 5:2)
Jesus was sweetly pleasing to our Father, while He suffered so and obeyed. He in us makes us how He is, or else we can not sweetly please our Father (1 Peter 3:4, 2 Corinthians 2:14-15), no matter what sacrifices we make (1 Corinthians 13:3). And I consider that only sweet-smelling people will stay with Jesus; God smells us.
But . . . also . . . there is plenty of positive sharing in the early scriptures. People so deeply appreciate the Psalms, which are so about God and trusting Him and how things go because of trusting God. And in the Psalms there is plenty about Jesus, though He is not directly named, including how it is to have Him as our Shepherd > Psalm 23, known by many as the "Twenty-third Psalm".
So, if someone says there is very little "written" about Jesus in the early scriptures, this could mean very little has been "read" by that person who says this
Or, very little has been "remembered". And it needs to be understood, of course.
But, like I mean . . . without Jesus in us as our light of God's love . . . none of us has very much "chance" of "getting" what a scripture means . . . the love meaning, the love application. Jesus in us is the living and the loving meaning of God's word.
It is like how you can have an automobile owner's manual, but if you have never seen or touched a car, your chances of understanding the manual are "interesting".
Or . . . imagine if you were a hula dancer in Hawaii and never have you been where it can get cold. And online you connect with an Eskimo who lives in an igloo, and he has you come up to visit him, for Christmas. Well, you dress in your best grassy skirt but putting on an extra layer of grass since he says you will need to dress with "layers" for the cold
And you get off the private plane on the ice, at his igloo, and you don't even know "why" you are shaking so much when you aren't even trying to dance. They take you right into their igloo and decide they had better give you your Christmas presents, right away . . . a parka, mukluks, pants, puffy and fluffy mitts. And, mmmm, you don't know what they are for! They have to tell you to put them on. Then is when you so appreciate these gifts that you didn't even know you needed.
Like this, Jesus is the gift we did not know we so needed. And only our Father knows what to have us do with Him. So, if being "rational" hasn't gotten us with God in His love and joy and peace, there is a "reason" for this.
"'Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.'" (Matthew 11:29)
