Is Success Necessary?
When given a job by God, we're expected to do it well with excellence giving all of the glory back to Him. The result is everyone around us will also give glory to God, notice Him, wonder who He is and why we follow Him.
That is the definition of success to God.
The world recognizing us, giving us accolades?
That's not the point, or part of the job.
"Whatever you do, do your work heartily, as for the Lord rather than for men, knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve."
