What the New Testament does not give us is explicit Trinitarian language saying that Jesus is God Himself..

On the contrary, Jesus even claimed to forgive sins, for which He was charged with blasphemy (Mk 2:5–7), because He was fully aware only God can forgive sin.
In perhaps the clearest indication of His claims about Himself, when the high priest asked Jesus if He was the Christ, the Son of God, Jesus plainly declared that He was. Then He further asserted that He was also the Son of Man who would coreign on God’s throne and come on the clouds in judgment. The high priest pronounced these claims blasphemy (Mk 14:61–64). Judgment is reserved for God alone.

GarySpFc: "Jesus even claimed to forgive sins, for which He was charged with blasphemy (Mk 2:5–7), because He was fully aware only God can forgive sin."

FRiend, the answer to your question is found soon after, in Mark 2:10-12:

Jesus answered them saying: 9 "Which is easier: to say to this paralyzed man, ‘Your sins are forgiven,’ or to say, ‘Get up, take your mat and walk’?
I want you to know that the Son of Man has authority on earth to forgive sins.”
So he said to the man, 11 “I tell you, get up, take your mat and go home.”
12 He got up, took his mat and walked out in full view of them all.
This amazed everyone and they praised God, saying, “We have never seen anything like this!”

Here again we see that Jesus clearly, consistently, openly said he was "Son of God", "Son of Man", Messiah/Christ.
He never explicitly claimed to be God Himself.
