Why can a believer be content with little in this 70-year life?
A believer can be content with little because this present 70-year life is not their heaven; God has prepared ages upon ages of unimaginable glory for those who love Him, making earth's best estates seem like a smelly pig pen by comparison. The best is yet to come.
Les explains that the unbelieving world has only about 70 years on average, and that is their heaven. But the believer has ages upon ages ahead, and that future makes this old world at its best look like a smelly pig pen. Les points to Scripture: eye hath not seen, ear hath not heard the things God has prepared for them that love Him. Therefore, he says he does not really care if we go through this 70-year life without much, because he does not need it; all the best is yet to come. This is not just for him, but for you and for everyone that believes. Earlier he also notes that God has made believers a new creature and new creation in Christ to bring glory to Him, not to live to self.
