The Apostle Paul seems to be such a perfect person. Before he was converted to faith in Jesus on the road to Damascus he appeared to be a perfect Jew. Once he was converted he appeared to be a perfect Christian, yet he was not.
When Paul left the city of Athens after proclaiming the Gospel to Jews and proselytes in the synagogues, to everyday people in the marketplace, and to philosophers in the Areopagus, he was worn out. Months before that he had been beaten, imprisoned, threatened, opposed, and forced to escape from city after city. In Athens, he faced the ridicule of the classically educated and convinced only a few that Jesus was God’s only way of salvation. He walked the 52 miles from Athens to Corinth, probably alone, and with little money. He learned both humility and reliance upon God in the early days at Corinth.
We, too, have such times in our lives when we feel alone and experience emotional emptiness and physical exhaustion. Yet that does not mean God has left us or we have left God. It means that we will realize and acknowledge His grace and strength to a greater degree as we are acutely aware of our own weaknesses. Like Paul in Corinth, that is not a bad place to be.
