Spend now, pay later

One difference between the fool and the wise man is that the fool will often spend now and pay later, and the wise man will save now and spend later. Learning to avoid the need for instant satisfaction, and being willing to sacrifice is a sign of maturity. 
Here are some examples,
1. Study and get an education now, and reap the benefits of a good Job later.
2. Patiently invest now, and reap a good return later.
3. Keep fit and healthy now, and be in good health when you get older.

When the devil temps a person, it is for instant pleasure at the cost of long term pain.  But when the Lord speaks to a person, it is often for initial sacrifice, for a long term benefit.  This is why it is always easier and pleasurable to listen to the devil, but in the end you'll always wish you listened to the Lord.
