To him who loves us and has freed us from our sins by his blood and made us a kingdom, priests to his God and Father. This verse describes not what you should become but what you already ARE: a king and priest.
Spiritual guidance begins with your identity. You are not a petitioner but a royal child. And as a priest you have direct access to the Father, without mediator, without waiting list.
Guidance through the Spirit becomes natural when you know who you are: loved, redeemed, appointed.
