A Waste of Time and Effort?
  It may seem to some that preaching the gospel is a waste of time and effort because most just brush it aside without even giving it serious consideration. That is tragic. But doing what God wants done is NEVER a waste of time and effort regardless of the results. People destroy themselves to reject Him.

  People ask, "Who won the debate?" with reference to the political arguments. Listening to the pundits you could never know because as far as they are concerned they had their minds already decided long before the debates began. Many are that way about the gospel of Christ. These debates are probably a waste of time and effort, but preaching the gospel is always " in season" and profitable for those whose mind is open and those who want and love truth.
