The Apostle Paul tells us that there are some things a Christian does that is not morally wrong, but may not be profitable in the sense that it does not build up others’ faith. In this verse, he urges the Christian to consider the impact of his action on the spiritual life of others around him. If it does not build others in the faith but potentially may be a stumbling to them, he says it is “not expedient” or “not profitable” to engage in it.
