2CO 4:2 Rather, we have renounced secret and shameful ways; we do not use deception, nor do we distort the word of God. On the contrary, by setting forth the truth plainly we commend ourselves to every man's conscience in the sight of God. 3 And even if our gospel is veiled, it is veiled to those who are perishing. 4 The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God. 5 For we do not preach ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus' sake. 6 For God, who said, "Let light shine out of darkness," made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ.
Does the dust refers to the “ashes” of the unbelievers who will soon perish?
MT 22:44 " `The Lord said to my Lord:
"Sit at my right hand
until I put your enemies
under your feet." `
RO 16:20 The God of peace will soon crush Satan under your feet.
The grace of our Lord Jesus be with you.
2CO 6:14 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? 15 What harmony is there between Christ and Belial? What does a believer have in common with an unbeliever? 16 What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: "I will live with them and walk among them, and I will be their God, and they will be my people."
2CO 6:17 "Therefore come out from them
and be separate,
says the Lord.
Touch no unclean thing,
and I will receive you."
Looking on the surface of Paul’s letters, the Bible.
2CO 10:7 You are looking only on the surface of things. If anyone is confident that he belongs to Christ, he should consider again that we belong to Christ just as much as he. 8 For even if I boast somewhat freely about the authority the Lord gave us for building you up rather than pulling you down, I will not be ashamed of it. 9 I do not want to seem to be trying to frighten you with my letters.
1CO 1:18 For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 19 For it is written:
"I will destroy the wisdom of the wise;
the intelligence of the intelligent I will frustrate."
1CO 1:20 Where is the wise man? Where is the scholar? Where is the philosopher of this age? Has not God made foolish the wisdom of the world? 21 For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe. 22 Jews demand miraculous signs and Greeks look for wisdom, 23 but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, 24 but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God. 25 For the foolishness of God is wiser than man's wisdom, and the weakness of God is stronger than man's strength.
