Last Sunday during the morning class when we were doing the readings it was mentioned that Achan, the man who caused great trouble for Israel when he took certain treasures from Jericho, acted upon the things of the world. That is, his sin followed the pattern given to us by John in 1 John 2:16,

"For all that is in the world,

the lust of the flesh,

and the lust of the eyes,

and the pride of life,

is not of the Father, but is of the world."
