I believe a fundamental postulate related to Christology is at the root of this question.

The question of twins points into a “duality” to be found in Christ, Our Head and True High Priest. There is no duality in His Incarnation and the quality of True God and True Man found only in His being. The Son is not only True God and True Man, not divided yet not mixed, He is also the Second Person of the Holy Trinity of God The Father, The Son and the Holy Spirit.

This leads me to state that the Bible is not hate speech whether or not you agree that there is sin present on our world. I pray that you discover the truth of our disobedience and offense to the thrice Holy God before the sun sets on Good Friday. Me He walk with you on Easter Sunday and every day of your life.
