As did Paul, those conscious of their spiritual need say: “Having sustenance and covering, we shall be content with these things.” (1 Timothy 6:8) Why? Because the satisfying of spiritual needs is what leads to eternal life.—John 17:3.
Is there anything wrong with enjoying good things if we have the money to buy them? Possibly not. Still, it strengthens our spirituality to learn not to indulge every whim or to buy something just because we can afford it. We thus learn contentment and maintain happiness, as did Jesus, even though his economic situation was not the best according to worldly standards. (Matthew 8:20) And Paul was not expressing unhappiness when he wrote: “I have learned, in whatever circumstances I am, to be self-sufficient. I know indeed how to be low on provisions, I know indeed how to have an abundance. In everything and in all circumstances I have learned the secret of both how to be full and how to hunger, both how to have an abundance and how to suffer want.”—Philippians 4:11, 12.
