what does it mean to reach across denominational lines without being ecumenical?
Reaching across denominational lines means recognizing that God has people for Himself in every group and reaching them, while refusing to compromise truth for unity. It is not ecumenism, which compromises doctrine to achieve unity; rather, it holds to truth while recognizing God's own in every group.
Les explains that he likes to reach across denominational lines because God knows that in every group there are people He wants for His own. However, he is not an ecumenicalist; he will not compromise in order to have unity. The apostle Paul rebukes division, asking 'Is Christ divided?' and reminding believers that Paul was not crucified for them. Unity is not achieved by compromising the gospel but by recognizing that Christ alone is the object of faith, and God has His own in every denomination.
