I like to think God realized we could never understand the full implications of the trinity (God, Jesus, and Holy Spirit all in one but separate). I agree with the blogger who said "It is difficult to use human language to describe the relationship between Jesus and God the Father without using metaphor. To describe it as a "biological" relationship seems misleading, since biological relationships are between created beings. If the word is used to convey the idea that the very life of the Father is fully expressed in his Son, it may be helpful."
So my takeaway is God is telling me to think like Jesus is his biological Son. That way I can better relate to the author of Hebrews and to Jesus and God. Pretty smart, that God is!
