In thinking of this idea of hatred and love, I think the question is our being allowed to know God and Jesus for those He has saved, and Jesus not knowing those who are not saved.
Afterall, Jesus tells those headed to hell and the second death, HE NEVER KNEW THEM and tells them to depart you workers of evil.
Matt 7
21 “Not every one that saith unto Me, ‘Lord, Lord,’ shall enter into the Kingdom of Heaven, but he that doeth the will of My Father who is in Heaven.
22 Many will say to Me in that Day, ‘Lord, Lord, have we not prophesied in Thy name, and in Thy name have cast out devils, and in Thy name done many wonderful works?’
23 And then will I profess unto them, ‘I never knew you: depart from Me, ye that work iniquity.’
Matt 25
41 “Then shall He say also unto them on the left hand, ‘Depart from Me, ye cursed, into everlasting fire prepared for the devil and his angels.
Have you not read about us knowing Jesus that it is only for those to whom Jesus and God choose to reveal themselves that end up knowing Them? And that knowing them means they are saved.
Luke 10
21 In that hour Jesus rejoiced in Spirit and said, “I thank Thee, O Father, Lord of Heaven and earth, that Thou hast hid these things from the wise and prudent, and hast revealed them unto babes. Even so, Father, for so it seemed good in Thy sight.
22 All things are delivered to Me by My Father, and no man knoweth who the Son is, but the Father; and who the Father is, but the Son and he to whom the Son will reveal Him.”
And John 17 as well talks of these things.
These words spoke Jesus and lifted up His eyes to Heaven and said, “Father, the hour is come. Glorify Thy Son, that Thy Son also may glorify Thee,
2 as Thou hast given Him power over all flesh, that He should give eternal life to as many as Thou hast given Him.
3 And this is life eternal: that they might know Thee, the only true God, and Jesus Christ whom Thou hast sent.
As far as hatred, yes God hates with divine red hot hate all workers of iniquity.
Matt 25
41 “Then shall He say also unto them on the left hand, ‘Depart from Me, ye cursed, into everlasting fire prepared for the devil and his angels.
As opposed to Ephesians 1 and 2, regarding the saved elect it is taught for and addressed to all the saints (those who believe and are saved).
Paul, an apostle of Jesus Christ by the will of God, To the saints who are at Ephesus, and to the faithful in Christ Jesus:
2 Grace be to you and peace from God our Father and from the Lord Jesus Christ.
3 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ, even as
4 He hath chosen us in Him before the foundation of the world, that we should be holy and without blame before Him in love,
5 having predestined us to be His own adopted children by Jesus Christ, according to the good pleasure of His will,
6 to the praise of the glory of His grace, wherein He hath made us accepted in His Beloved:
See He has done this for his own Glory.
And Eph 2
And you He made alive, who were dead in trespasses and sins,
And why does He do this, the answer is in v3, Love, His great love for His elect.
4 But God, who is rich in mercy,
because of His great love with which He loved us, 5 even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved),
The relationship is in God knowing us, with Love towards His elect and that is why anyone gets saved by Him, due to His GREAT LOVE towards His elect. Even before they are saved, His calling regarding our election stands and they will come to know Him at the appointed time of His own choice.
