(2 Tim 3:1-4) But mark this: There will be terrible times in the last days. People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, treacherous, rash, conceited, lovers of pleasure rather than lovers of God
So, the adage, "survival of the fittest" rages on! To each his own! The rat race will not stop until the final cheese gets wholly gobbled up.
And then there is this number 7 thingy. It speaks of completeness in God's Word and perhaps, 7 billion would be another sign of the soon coming of Christ!
What Christians ought to do....
1. Live simple lives. Don't go into heavy debts or at all.
2. Have that theme in life, eat to live and not live to eat.
3. Be the light and salt to your world!
4. Glue your eyes to Jesus as you serve Him!
5. Always be aware that you are not just a statistic in the 7-billion-people world but a significant individual God can use for His kingdom!
