No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon. (The words of Jesus, quoted in Matthew 6:24 and Luke 16:13.)
Here is a stark warning that the pursuit of spiritual gain and the pursuit of material gain are not compatible. In such a materialistic age as we live in it is hard for us to fathom that this could be true. Yet here is another pronouncement of Jesus for reinforcement:
Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed? (For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things. But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. (Matthew 6:31-33).
Here is a clearly stated promise that if we make spiritual gain our goal, we will not suffer material ruin. On the other hand, it is clearly implied that to make material gain our main priority will lead to spiritual ruin.
This is a basic truth that is supported by many other statements throughout the New Testament. There is nothing in the New Testament to suggest that the pursuit of material gain will be beneficial to our spiritual life.
We must also resist the temptation to make either poverty or prosperity the gauge of a person’s spiritual life. North America is a land of opportunity and many Christians here have attained to a level of prosperity that is well above that of most Christians in other lands. This is no proof that we are more spiritual than they are, or that God is more pleased with us.
There are people in North America who have been denied access to the opportunities most of us take for granted. Others, for various reasons, seem unable to see or to manage the opportunities that are available to them. This is not proof that they are less capable of spiritual gain or that God is angry with them.
According to the social conscience of our time, material poverty is the one great sin of our society. In the light of eternity, the spiritual poverty of those who live for ease and pleasure is the great sin that will bar them from heaven.

“North America is a land of opportunity and many Christians here have attained to a level of prosperity that is well above that of most Christians in other lands. This is no proof that we are more spiritual than they are, or that God is more pleased with us.” <—- That right there is the crux of why religious channels like TBN drive me crazy. The "Prosperity gospel" junk that convinces already-struggling people to send their money to these "pastors" because God will bless them for their charity. It makes me SO angry!
I agree. The prosperity gospel is a threat to all Christians, because it plants the idea that our assurance of salvation is based on the abundance of our material possessions. This is the reason the apostle Paul said that covetousness is idolatry; it leads to putting faith in material possessions rather than in God alone..
TBN has been a great blessing to me. However, let us not judge the channel as a whole against the sins of a few, otherwise we’d need to cut off our Christian radio stations, stop paying for internet, cable, movies, and Christian publication media and gifts just to keep it real.
Philippians 1:18 KJV
What then? notwithstanding, every way, whether in pretence, or in truth, Christ is preached; and I therein do rejoice, yea, and will rejoice.
