A few examples...
John 1:10, He was in human society, and humanity came into being through Him, and humanity did not acknowledge Him.
John 1:29 The next day he *saw Jesus coming to him, and *said, “Behold, the Lamb of God who takes away the sin of humanity.
John 3:16 God loved humanity in this way, He gave His uniquely divine Son so that everyone believing into Him would not perish but have everlasting life.
John 6:33 For the bread of God is that which comes down out of heaven and gives life to humankind.
John 6:51 I am the living bread that came down out of heaven; if anyone eats from this bread, he will live forever; and the bread which I will give for the life of humankind also is My flesh.”
John 8:26 “I have many things to say and to judge regarding you, but He who sent Me is true; and the things which I heard from Him, these I say to humanity.
John 12:47 “If anyone hears My teachings and does not keep them, I do not judge him; for I did not come to judge humanity, but to save humanity.
John 13:1 Now before the Feast of the Passover, Jesus, knowing that His hour had come that He would depart from this human society to the Father, having loved His own who were in human society, He loved them to the end.
John14:31 but so that humanity may know that I love the Father, I do exactly as the Father commanded Me. Get up, let’s go from here.
John 16:28 “I came forth from the Father and have come into human society: again, I am leaving human society and going to the Father.”
John 17:6 “I have revealed Your name to the men whom You gave Me out of humanity; they were Yours and You gave them to Me, and they have followed Your word.
John 17:21 that they may all be united; just as You, Father, are in Me and I in You, that they also may be in Us, so that humanity may believe that You sent Me.
1 John 2:15-17 Do not love human society nor the things of human society. If anyone loves human society, the love of the Father is not in him. For all that is in human society, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from humanity. Fallen human society is passing away, and also its lusts; but the one who does the will of God lives forever.

And WHY use "humanity" in some places, and "human kind"in others? The later is fine in all places.
