Look at the world today. Problems around are not caused by lack of resources but the enormously of human greed. So the earth has got created, it's good and sufficient.
It can provide for everyone's needs but as that wise saying goes, the earth has enough for man's needs but not for man's greed. So this is a simple truth which explains why so much injustice exists today.
We have been reminded that greed has corrupted our minds. If you control most of the world's heads, why millions suffer in hunger and despair? So it's not that God has failed humanity but humanity has failed God by turning away from the path and commandment of God.
So amid all this, tribulation has also superseded. As he said, the teachers, patients, strength and account and give back to robots, even Christ himself, also faced so many tribulations. And told us to be good and told us to be of good cheer because he has already overcame the world.
If we can overcome greed with love, patience and obedience to God, then we can help to restore justice and peace to our troubled world as we progress.
Stay Blessed.
