These are 3 ways that God works. God the Father created the heavens and the earth. God the Son came to be the holy sacrifice needed to free us from the bondage of sin. God the Holy Spirit guidance our souls to making Holy choices.
I, as a person, can fill different roles but am one person. I am a mother: I grew my child in my womb and am responsible for him. I am a wife: I serve my husband. I am a daughter: I was given by my parents and honor them. 3 roles, one person.
