Sonship is as simple as travelling to the center of Him, to be IN YHVH.
As you Jesus is the example of how to be and live as a son of God. Especially since He is the first of many sons. We also know that Jesus only did what He saw the Father doing. So a key to living as a son is to see as the Father sees or to see from the Father's perspective. That perspective is from "in Him". “In Him is the PLACE”. You also know that "In Him" all things are possible - another son of God attribute. This and more are demonstrated by the life of Jesus. But it is also demonstrated in His name. The Hebrew name of Jesus is Yeshua. Yeshua is created by placing a "Shin" (ש) in the middle of YHVH. So Yeshua is YHשHV. You can not be a true son unless you are living "in HIM". So we can be as the living being " ש " and abide in YHVH and be also a son of God just like Jesus (YHשHV).
Elijah said, "Return often to this place, return to this mountain (Hebrews 12:22). Do not come with only the intention of engaging me, the chariot, the winds... but come with the intention to continue your transfiguration. It is written (Matthew 17), that sons go up into the mountain to be changed and to receive council. This is also known as coming boldly before His throne (Hebrews 4:16) this is a way of being who you are; this is the way. Return often to this place; return to this mountain".
