Michael, I understand better now what you meant.
Note, however, that Prophet Elijah failed in his mission as well, told God as much, and God reassured him all that really mattered was that he had done what he was commissioned to do (1 Kings 19:11–16). God in fact gave him some more work to do, this to a man who just failed at turning people to God.
Guess what happened to Elijah? God took him to heaven without seeing death (2 Kings Chapter 2).
God took a prophet who did not turn a single Israelite from idolatry to faith in Him to heaven without seeing death.
The prophet that followed Elijah, Elisha? Worked miracles, the people did not change. Jeremiah, Ezekiel, Amos in the Bible? All prophets who failed to change the people.
Samuel answered God’s call, “Here I am send me.” The people rejected God (1 Samuel 8:7).
Apostle Paul was chased out of some cities with whippings and stonings (Acts 14:19), yet is one of the greatest apostles of Jesus Christ.
God does not judge us by our success at winning people over to Him. He judges us by our faithfulness to Him. Anyone considering you a failure for not succeeding at your mission does not really know God like he or she ought to.
How do I know this? Is it you or I who changes people to know God?
I planted, Apollos watered, but God gave the increase. So then neither he who plants is anything, nor he who waters but God who gives the increase (1 Corinthians 3:6–7).
It is God, Jehovah, Father of our Lord Jesus Christ who gives the growth to any work that we do, not arbitrarily, but on basis of people’s response to Him.
God is not interested in numbers. He is interested in genuine responses to His love. He would rather have 100 genuine responses that takes 10 years to nurture, than 100,000 immediate responses that are nothing but fluff. Jesus exemplified this choice. He fed 5,000 at one time, 4,000 at another time, yet had no more than 500 disciples at time of His ascension to heaven.
Jesus chose genuineness over fluff.
I hope you find some comfort in these truths.
