Moreover it is required in stewards that one be found faithful.
The apostle Paul described himself as a servant of Jesus Christ entrusted with the responsibility to be a steward of “the mysteries of God” (1 Corinthians 4:1).
“A steward was a slave who administered all the affairs of his master’s household, though he himself owned nothing. … Joseph held such a position in the household of Potiphar (see Gen. 39:2-19)” (Nelson’s NKJV Study Bible, note on 1 Corinthians 4:1).
Paul took his stewardship seriously and strove to faithfully please the Master, Jesus Christ. He was not trying to gain a following for himself and was unhappy that factions were forming in Corinth. He knew the judgment that counted was not the unfair judgments of his detractors in the Corinthian congregation, but the judgment of God (1 Corinthians 4:3-5).
