What does the eye being single mean? ἁπλοῦς haploûs, hap-looce'; probably from
G1 (as a particle of union) and the base of
G4120; properly, folded together, i.e. single (figuratively, clear):—single. (Strong's definition) This is the adjective form of the noun ἁπλότης haplótēs, hap-lot'-ace; from
G573; singleness, i.e. (subjectively) sincerity (without dissimulation or self-seeking), or (objectively) generosity (copious bestowal):—bountifulness, liberal(-ity), simplicity, singleness. G4120 which the word is rooted in literally means to plait, braid, weave together, as in a rope or more importantly as in the fringe of a garment, (Think In terms of Hebrew fringe of their garment).
And it shall be unto you for a
fringe, that ye may look upon it, and remember all the commandments of the LORD, and do them;
and that ye seek not after your own heart and your own eyes, after which ye use to go a whoring: (Num. 15:39)
Notice again the contrast between Natural eyes and Spiritual eyes, the fringe being what reminded them of the Glory of the LORD which they saw at mount Sinai, So Your eye being single, points directly to the Glory of the LORD. Which contrasts with the heart that is natural and eyes that see the natural that goes after harlotry.
WE as believers are earthen vessels, We are the temple now, and the Glory of the LORD is within us. When a gift of discerning of the spirits falls on a person they see this light in the believers, and see its absence in unbelievers. The Artistic concept of a Halo is not even close to what is seen though I suspect this is how early believers who had this gift tried to express it. What I can tell you is that this light eminates from the saints, But not from the faithful in Christ Jesus, although their eye is not darkness as is the case of the Wicked. To Put it another way, Some believers have yet to put on their armor of Light, Because they have yet to see their need to do so (Read Romans 13:12-14 here) Nor do they understand how to.
Now let's speak of the implications of this for end times. We are speaking of Spiritual eyes to see what is light and what is darkness, what you have with this outpouring is the revelation of the Spirits at work in people whether the Holy Spirit, Or demonic spirits. This revelation will allow us to have the man of sin revealed before the end, the Antichrist. This will allow us to hear the trumpet call of the LORD, to see the heavens open up like a scroll, to see the stars falling from heaven, This is the very gift that John had when he saw the visions of Revelation, this is the very Gift that Paul was given when he was carried away to third heaven And these sorts of visions are what will manifest in the end times church when this gift falls upon them, the rest will fall into the strong delusion and believe the lie.
Imho we should all be desiring and wanting this final outpouring upon us, as those who do not receive it WILL fall away. The harvest is plentiful, but the laborers are few.... So few in the church see and acknowledge the need to even explain what this gift of discerning of spirits involves. Most assume they have it because they have a modicum of discernment from the Holy Ghost, But not the gift. You can even have people doing deliverance ministries who do not have this gift, thinking they do, as Jesus said "he never Knew them" (Matthew 7:22-23)
But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. But God hath revealed
them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. (1 Cor. 2:9-10)
May His Spirit reveal the deep things of God to you!
