“Here I am. Testify against me before Jehovah and before his anointed one: Whose bull or whose donkey have I taken? Or whom have I defrauded or crushed? From whose hand have I accepted a bribe to make me look the other way? If I have, I will restore it to you.”
~1 Samuel 12:3
Samuel had a clean conscience because he maintained sincere, wholehearted worship of Jehovah throughout his life.
The people he served were able to testify: “You have not defrauded us or crushed us or accepted anything at all from anyone’s hand,” (1 Sam. 12:4).
While leaders of false religion use their religious institution as a sort of business and as a means to sustain themselves materially, true believers do not take advantage of their spiritual brothers to gain material benefits (Matt. 10:8; 1 Pet. 5:2).
We must be careful to always keep our form of worship free of commercial or potentially corrupt personal interests in order to not imitate the oppressive attitude of hypocritical church leaders (John 2:15,16).
Then we should ask ourselves: can I swear before Jehovah, like Samuel, that I have defrauded no one?
