The bible is very clear on the issue pertaining to gender, in the old testament and in the new because God’s word does not change. Here are some biblical proof;

Genesis 1:27: So God created man in his own image, in the image of God created he him; male and female created he them.
Mark 10:6: But from the beginning of the creation God made them male and female (This was uttered from the mouth Jesus Christ)

Now this is the design God has made anything than the these are truly a perversion of the Creator’s plan. This is a deception from the devil to create confusion in the masses because “For God is not the author of confusion, but of peace, as in all churches of the saints” 1 Corinthians 14:33 For if it is of God it will not go against His word and against His nature.
