The letter of the word can never fully teach one what they need to know, for each person must come to the place of seeing God, as He is, which brings a person to a change of thinking.
Set your affection on things above, not on things on the earth. Colossians 3:2
Affection ------ to have understanding, be wise
When Jesus came out of the water and the heavens opened to him, revealing He was to relentlessly seek those things which were above his earthen heritage.
I see this shows us that sons are to give their thinking to those things that are above and not to the things on the earth.
Malachi 3:3 ----- And he shall sit as a refiner and purifier of silver: .....
Why does he sit as a refiner?
Does the act of sitting have a purpose in the purifier of silver?
Yes it does for as the silver smith watches the silver be purified over the fire if he forgets about it the fire will destroy the silver.
So the silver smith sits watching the silver in the fire until he sees his image in the silver; that is when he knows it is pure and removes the silver from the fire.
