Why do missionaries leave their families and native country to labor in distant lands? Why do Christian workers (teachers, secretaries, etc.) labor in ministries instead of working in higher paying positions in the world? Why do most believers cheerfully give from their income to the local church when they could spend it on things of pleasure? Why do Sunday School and Bible teachers sacrifice their time to prepare for their ministry to the saints instead of using that time for leisure? Why do so many believers make it a priority to set aside time to consistently be in Bible class, the preaching hour, and mid-week prayer and study services when they could choose to spend this time at work or play?
The answer to the above questions is found in II Corinthians 4:18: “We look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.” You see, a truly spiritually minded believer does NOT simply live for this life alone. Instead, he weighs his present actions and choices from a heavenly and eternal perspective of gain or loss. He is able to look at today’s time, ministry, finances, and choices as an opportunity to invest in eternal future reward, and he is motivated to do so with consistency, diligence, and joy.
How have you been looking at your life? Have you been only looking at the “things which are seen,” or have you been looking at, and valuing most highly, the things which are eternal? This may be a good day to change focus and priority. source
