An excerpt from "Got Questions.org" entitled, "What does it mean that we are not to cause others to stumble?" states: "The Greek word for “stumble” gives the sense of stubbing one’s toe. As Christians, we are forbidden to do anything that may cause our brothers and sisters in Christ to stub their toe, spiritually speaking. Stubbing the toe can cause a person to fall in the spiritual sense, or to damage or weaken his faith. In all things, the important lesson is to “make every effort to do what leads to peace and to mutual edification” (Romans 14:19). In this way, God is glorified, believers are edified, and the world sees in us “righteousness, peace and joy in the Holy Spirit” (Romans 14:17)."
