To SEE spiritually requires a letting go of the flesh. Not in the literal sense but the spiritual. Allowing your true nature which is the soul to be the forefront of your conscious mind.
There is a game I play with my children to strengthen their spiritual sight. I call it “see without seeing”. I have them sit with eyes closed and identify objects, colors or what they see around the room without their eyes. Then we go deeper I put YouTube instrumental music with video and have them identify what is on the screen without eyes.
As a SEER or interpreter you must develop the ability to deny the flesh and follow HIM! “for we walk by faith, not by sight” 2 Corinthians 5:7 AMP “That which is born of the flesh is flesh [the physical is merely physical], and that which is born of the Spirit is spirit.” John 3:6 AMP
