*** w06 3/15 pp. 24-25 par. 15 "Each One Will Carry His Own Load" ***Often, the choices we make affect others, and we need to give consideration to this. The first-century Christians, for example, were no longer under many of the dietary restrictions of the Mosaic Law. They could choose to eat certain foods that were considered unclean under the Law and were not objectionable in other ways. However, the apostle Paul wrote about meat of an animal that might have some link with an idol temple: "If food makes my brother stumble, I will never again eat flesh at all, that I may not make my brother stumble." (1 Corinthians 8:11-13) The early Christians were encouraged to show consideration for the consciences of others so as not to stumble them. Our decisions should not make us "causes for stumbling."—1 Corinthians 10:29, 32.

Whatistheeffectofdoingthework;willithurtone’sownconscienceorstumbleothers? Conscience should be considered, both our own and that of others. Even if a certain work (including its location and source of pay) seems acceptable to most Christians, an individual may sense that it would trouble his personal conscience. The apostle Paul, who set a fine example, stated: "We trust we have an honest conscience, as we wish to conduct ourselves honestly in all things." (Hebrews 13:18) We ought to avoid doing work that would leave us disturbed; yet, we also should not be critical of others whose consciences differ. Conversely, a Christian might see no conflict with the Bible in his doing a certain work, but he realizes that it would be very disturbing to many in the congregation and in the community. Paul reflected the right attitude in his words: "In no way are we giving any cause for stumbling, that our ministry might not be found fault with; but in every way we recommend ourselves as God’s ministers."—2 Corinthians 6:3, 4.
