I see no short simple answer for the first part: God loves everyone. But, consider the following:
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." John 3:16
What is the "world" that God loved? From the context of the verse it appears to me that it was people, people to whom He granted a means by which they need not ever die. It does not, however, say that He loves all people. Consider these verses:
"I have loved you, saith the LORD. Yet ye say, Wherein hast thou loved us? Was not Esau Jacob's brother? saith the LORD: yet I loved Jacob,
And I hated Esau, and laid his mountains and his heritage waste for the dragons of the wilderness." Mal 1:2-3
It seems that God who is Love according to scripture did not love Esau. Why not? Was it that Esau in the final totality of him was found here among the things that God hates?
"These six things doth the LORD hate: yea, seven are an abomination unto him:
[1] A proud look,
[2] a lying tongue,
[3] and hands that shed innocent blood,
[4] An heart that deviseth wicked imaginations,
[5] feet that be swift in running to mischief,
[6] A false witness that speaketh lies,
[7] and he that soweth discord among brethren." Prov 6:16-19
Reference was made also this verse on this thread:
"For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord." Rom 8:38-39
So then once we have it [the love of God] none of those things can separate us from it. But... can we walk away from it or cast it away from ourselves?
"For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
And have tasted the good word of God, and the powers of the world to come,
If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame." Heb 6:4-6
That does not sound to me like a person could not walk away or cast away the enlightment received, the gift received, the Word of God tasted even though he of course should not. Could that or would that, however, be the unforgivable sin?
Another question we might ask is, Can God loves someone He hates? Can we?
I remember a young lady I knew when I was in college who had a young daughter. She married the father momentarily to give the child legitimacy. She told me she hated her daughter because of what her existence had done and continued to do to her life... her "freedom". At the time she said she loved for daughter for being the sweet little person that she was, the fruit of her own body.
So then again the question: Can God love someone He hates? Could He for example have loved Esau whom He hated?
On the second part, God forgives everyone, consider these words:
"For if ye forgive men their trespasses, your heavenly Father will also forgive you:
But if ye forgive not men their trespasses, neither will your Father forgive your trespasses." Matt 6:14-15
.
Consider this brother, (Rom. 9:8-13), "...For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;....As it is written, Jacob have I loved, but Esau have I hated."
