It is your entering into the word that produces results. No entrance no rewards. Deu.28:1-3. Jos. 1:8. The word you hear does not produce any value, it is the word you obey and the level of your obedience that count. If they obey and serve me, they shall spend their days in prosperity and their years in pleasure. Job.36:11. “Behold I come quickly my rewards are with me to give every man according to his work.” Rev.22:12. So, serving God is work, is a big time business that yield the most profitable rewards. Anything can fail. But not like tireless obedience. Jesus said He must be about His father’s business. Lk.2:49. Not He may be. It is a must. No body knows the functions of a product better than the manufacturer. God knows you better.
