So, you know how sometimes people talk about God? Well, sometimes they also talk about the Holy Spirit, who is a part of God. Some people refer to the Holy Spirit as "he" and others refer to the Holy Spirit as "it". But you might be wondering, "if the Holy Spirit is part of God, why isn't it referred to as 'she' too?"
Well, the thing is, God doesn't have a gender like you and me do. When we say someone is a boy or a girl, we're usually talking about their body parts - like if they have a penis or vagina. But God, and the Holy Spirit, don't have a biological body.
So, even though some people say "he" when they talk about the Holy Spirit, that's just another way of saying "it". It's like calling your teddy bear "he" even though it doesn't have a real gender.
So, in conclusion, the Holy Spirit doesn't really have a gender because it's a part of God and God doesn't have a body like we do!
