Donald Trump doesn’t concern me. He is not a minister.
If 2 Corinthians 8:9, which you quote above, is about Christ making believers millionaires by becoming poor, we’d all be financially rich.
Paul talks about “the nation’s riches” which are not financial riches but rather spiritual riches.
Yes, and rightly so that A.E. Knoch would have a different understanding which is more scriptural.
Here are the verses in Paul’s epistles concerning riches:
Rom_2:4 Or are you despising the riches of His kindness and forbearance and patience, being ignorant that the kindness of God is leading you to repentance?
Rom_9:23 it is that He should also be making known the riches of His glory on the vessels of mercy, which He makes ready before for glory -"
Rom_11:12 Now if their offense is the world’s riches and their discomfiture the nations’ riches, how much rather that which fills them!"
Rom_11:33 O, the depth of the riches and the wisdom and the knowledge of God! How inscrutable are His judgments, and untraceable His ways!"
2Co_8:2 for, in a test of much affliction, the superabundance of their joy and the corresponding depth of their poverty superabounds to the riches of their generosity,
Eph_1:7 in Whom we are having the deliverance through His blood, the forgiveness of offenses in accord with the riches of His grace,
Eph_1:18 the eyes of your heart having been enlightened, for you to perceive what is the expectation of His calling, and what the riches of the glory of the enjoyment of His allotment among the saints,
Eph_2:7 that, in the oncoming eons, He should be displaying the transcendent riches of His grace in His kindness to us in Christ Jesus."
Eph_3:8 To me, less than the least of all saints, was granted this grace: to bring the evangel of the untraceable riches of Christ to the nations,
Eph_3:16 that He may be giving you, in accord with the riches of His glory, to be made staunch with power, through His spirit, in the man within,
Php_4:19 Now my God shall be filling your every need in accord with** His riches in glory in Christ Jesus**.
Col_1:27 to whom God wills to make known what are the glorious riches of this secret among the nations, which is: Christ among you, the expectation of glory"
Col_2:2 that their hearts may be consoled, being united in love, and to all** the riches of the assurance of understanding**, unto a realization of the secret of the God and Father, of Christ,
1Ti_6:17 Those who are rich in the current eon be charging not to be haughty, nor yet to rely on the dubiousness of riches, but on God, Who is tendering us all things richly for our enjoyment;"
Financial riches are dubious at best and fleeting. The riches of Christ is what remains. In this sense, I would take the riches of Christ over all the financial riches of the world.
