"You lie on beds adorned with ivory and lounge on your couches. You dine on choice lambs and fattened calves." NIV translation
Now, Amos gives us more details about what was going on with the high society folks of the northern kingdom. Here, we see the first of three sins which is gluttony. The rich folks were living it up and had forgotten the poor and the fact that all they had was a gift from God. The gluttony even extended into sexual immorality. They basically had the attitude that they earned and deserved this lifestyle even though it was contrary to the ways of God. They did their "religious duties" but did not let God into the rest of their lives. This is similar to what is happening in our world today where many people do their "religious duties" on a Sunday and then its all about them the other six days of the week.
"You strum away on your harps like David and improvise on musical instruments." NIV translation
The second of the three sins is that they perverted the God given gift of music and it was no longer used to praise and glorify God. Music was initially used for praising God and, in fact, Satan was the leader of worship in heaven. Since his fall, he has been behind the decline in music to where it is today. Although there is some wonderful praise music and songs, the vast majority of music in the world today is about things that do not honor God. The danger in this is that what goes into your mind through your ears has an impact on the way you live.
"You drink wine by the bowlful and use the finest lotions, but you do not grieve over the ruin of Joseph." NIV translation
The final sin that Amos mentions is drunkenness. Although wine is a gift from God and even Jesus turned water into wine, the excessive use of it to get drunk is sinful. That brings up the question of why people get drunk and even become alcoholics. The simple fact of the matter is that people get drunk to forget that they are disobeying God. In the example of Israel, they were living it up and knew it was wrong but they could forget about the coming judgment for awhile by getting drunk. We easily forget that alcohol (when taken in excess) is a mood altering drug but at that point it is no different than any other illegal drug. As we see in Revelation 9 & the last days, people will turn more and more to drugs to try to escape the horrors of disobedience. All that is really needed is to accept Jesus Christ; He is the one step approach to recovery.
