“This is the time of fulfillment. The kingdom of God is at hand. Repent, and believe in the gospel.” Mark 1:15 
 
There are two invisible kingdoms – God’s and satan’s. How can we figure out which one we are living in?
St. Paul tells us in Acts 20:33-35 – “I have never wanted anyone’s silver or gold or clothing. You know well that these very hands have served my needs and my companions. In every way I have shown you that by hard work of that sort we must help the weak, and keep in mind the words of the Lord Jesus who himself said, ‘It is more blessed to give than to receive.’”
Paul is expressing how it is to live in the Kingdom of God.

* don’t envy other people’s possessions
* work hard to help the weak
* there is more happiness in giving than in receiving

If you want to see how it is to live in the kingdom of Satan, just reverse those.
