Family Radio believed that the Lord would return for all true Christians on those days but since "they" are obviously still here, God did not in fact return. They believe He will still come for true believers at an unknown date. They truly wish that God had returned for believers on either of those days. However, since God did not return for true believers, it is incumbent upon true believers to continue to preach the gospel until then. Of course they mean preach the gospel as they have defined it.
It was clear from this editorial that they still hold to the sinfully wicked false teaching that the church age has ended and that true believers are to leave their churches. The church age will end one day with the glorious return of our Lord Jesus Christ. Since He has not returned for His church (I Thessalonians 5) the church is alive and well. It is no secret that many of the visible representations of the glorious invisible church are heinous representatives. Christ promised that even the gates of hell would not prevail against the church. (Matthew 16:18)
What a great heartache it is to know that this organization with all of its tremendous resources remains heretical. My heart grieves for those who are deceived. Oh, that true followers of Jesus Christ would recognize the deception and false teaching and abandon this organization.
