But godliness actually is a means of great gain when accompanied by contentment. For we have brought nothing into the world, so we cannot take anything out of it either. If we have food and covering, with these we shall be content.
1 Timothy 6:6-8
The Apostles suffered for their faith and ministry. They were jailed and all but John, the Beloved, were martyred.
I think that is why Timothy wrote this, because he came to realize that the best of times were those times when he had just what he needed to survive - food and clothing and shelter. It was in these times that they were able to go about ministering, healing the sick and preaching the Gospel. They were not looking to become wealthy, but to live holy lives and serve God.
I think that we too can aspire to this - not that we will be poor - but to realize having what we need is a true blessing from God.
