If heavenly folk have no vagina, no penis and no breasts, in a world without marriage, how can we possibly call them male and female?
Galatians 3:28 (KJV)
...there is neither male nor female: for ye are all one in Christ Jesus.
Matthew 22:30 (KJV)
For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
Zechariah 5:9, does not contradict traditional beliefs of genderless angels, because it is about evil creatures with wings like a stork, biblically an unclean bird.
Jesus sacrificed His life of luxury to live in poverty with an excruciating sacrifice, because He loves you.
Could you give back some love to God, by making an easier sacrifice: your sinful acts to prove your love for God?
and we all be friends or angels in heaven i believed :)
