Why would people turn their back on the Good News? Do they think it's TOO good so it must not be true, or do they just hate the thought of some really bad people escaping eternal torment?
Beyond and above the working of the god of this age is the God of Jesus Christ. All things are worked by Him for His pleasure and purpose. Even those who have experienced God in the new birth and the baptism of the Holy Spirit are blinded to the evangel, or, "good news" because they are unbelieving. The Cherubim are still operating sWORDs of fire that turn in every direction to prevent access to the tree of life.
2 Corinthians 4
3-4 (Concordant Literal Translation)
Now, if our evangel is covered, also, it is covered in those who are perishing,
in whom the god of this eon blinds the apprehensions of the unbelieving so that the illumination of the evangel of the glory of Christ, Who is the Image of the invisible God, does not irradiate them.
2 Corinthians 4
3-4 (Young's Literal Translation)
. . . and if also our good news is vailed, in those perishing it is vailed, in whom the god of this age did blind the minds of the unbelieving, that there doth not shine forth to them the enlightening of the good news of the glory of the Christ, who is the image of God;
Subsequent to this exposure of the spiritual working of a veil (upon all peoples) which prevents the Glory (in which we are otherwise changed into the Divine Image,) the creation account is called upon as a parallel, the emphasis here being the world within. It is a re-creation for God to speak in order that our passions and motives, our knowledge also becomes illuminated so we come into the Glory, perceiving the true nature of Jesus who is anointed for us. We are dependent on God's freely speaking to us; or, darkness is upon the face of our waters and who we are cannot be ascertained.
Salvation, liberation, glorification and all God's work conforming us to the Image of His Son, are done in such a way that it is obviously accomplished by God. We don't, and indeed can't do these works, not even with the Holy Spirit's help. It is the Glory of God which He will not share with another. As long as belief is in ourselves God cannot honor our faith with His light, His speaking. But consider how it is that right now the treasure is in the physical realm, the dimension our bodies inhabit. That must be unveiled. We are going to manifest what God has wrought, the body being liberated by Glory. The power and radiance of God is exceeding great.
2 Corinthians 4
3-4 (Young's Literal Translation)
. . . because [it is] God who said, Out of darkness light [is] to shine, who did shine in our hearts, for the enlightening of the knowledge of the glory of God in the face of Jesus Christ. And we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us;
