If you light a single candle, it will provide some light. But if you add more candles with it, the light can become as bright as the day. In the same way, one Christian in your church can be a light in the community. But if you put other Christians and their churches together, Jesus said we become the "light of the world" (Matthew 5:14). We can do so much more together than we could by ourselves. By ourselves we are seen as partisan, out for our own end. But together in a crusade we have a united front as the body of Christ to a watching world. Luis Palau said, "United mass crusades tell the nation that we have a common core of biblical faith that binds us in love both to Jesus Christ and to one another. And that love makes a powerful impression. 'By this all men will know that you are my disciples,' Jesus said, 'if you love one another' (John 13:35)."

By ourselves we do not have the financial resources or contacts to make an impact for Christ. By ourselves we could never get the attention of the community and its leaders. But in a crusade people become God-conscious, asking questions about life, death, and the church. By ourselves we could not communicate the gospel truth to these multitudes. But in a crusade people who are searching for God come out from hidden corners. All of society is touched by a crusade, from the professionals and highly educated to the "untouchables" and homeless. Even the indifferent youth are attracted. A crusade sows the seed of the Word of God and reaps where others have sown. The many commitments and decisions made affect neighbors, friends, the church, and loved ones. Over and over again it has been proven that crusade evangelism helps the church and the community. Crusade evangelism accomplishes what the local church alone cannot do.
