Why did God create a bespoke Y chromosome just for Jesus? Why couldn’t Jesus have been born female? What would that change?
Because God is male. Man was created in God’s image, Jesus refers to God in heaven as Father, Jesus is a male (He was circumcised) and the Holy Spirit is also Male (as the Holy Spirit impregnated the Virgin Mary)
Why is God male? Does God have a Y chromosome? Does God produce sperm? Does God have testes?
