"...but speaking the truth in love, may grow up in all things into Him who is the head -- Christ -- from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share..." (Ephesians 4:15-16)
All who are members of this congregation need to be preparing for the upcoming gospel meeting. Each member needs to take advantage of the opportunities it affords for evangelism. Everyone has to do their part for the meeting to be a success and the cause of the Lord to prosper.
If we work, our efforts will bear fruit. We may not be overwhelmed by what many have termed "visible results" (such things as baptisms, restorations, etc.), those things so many want to guage the success of a meeting by, but we will be a church after the New Testament order at work the way the Lord wants it to work -- with each member doing his/her part (see 1 Cor. 12:12-27; Eph. 4:15-16).
At all times we ought to be emphasizing our responsibilities to evangelize. In doing so, though, we must realize that one person, or even just a few, cannot be as effective as a whole body of people actively involved in reaching and teaching other people. But gospel meetings provide unique opportunities to show that we are more than just talk when it comes to evangelism but are actually "doers of the word" (Jas. 1:22). They allow us to demonstrate to the Lord and to others that we are willing to be involved in His work.
The personal invitation extended to a friend, relative or acquaintance is still, I believe, the best method for getting people to attend gospel meetings. We can blitz the media using all the modern methods at our disposal but nothing can top the personal "one-to-one" invitation. Since this is the case, then, it makes sense that the more people who issue such invitations, the greater chance for success in having greater numbers attend.
I am sure the meeting preacher is doing his part to make the meeting successful. We have printed hundreds of fliers and are sending out announcements to other congregations. The key to real success, though, will be how many of the members personally invite others. That should not surprise you since the key to success in almost every work that we might be involved in as a church is great individual involvement.
May each of us be totally involved in serving the Lord -- not just for the upcoming meeting but in all aspects of the work of the church.
