“Whoever claims to love God yet hates his brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.” (1John4:20)
Therefore, mankind, with one voice, must first embrace the One from ABOVE–by virtue of being Son of Virgin, attested by both Bible & Quran. And for having said to have died for us–a supposed BIG lie—try Him/His Servants (Holy Spirit/Word — Jn6:63), before contemplating יהוה/God/الله/ईश्वर.
