The test of preaching ultimately is what men do about it. The decision is what counts. A sermon must move the human will to action if it is to accomplish its purpose (Rom. 10:13). The truth of the message is saved from degenerating into mere rationalism on the one hand and emotionalism on the other by giving it some proper expression. In fact, to stir people religiously without helping them do something about it leaves them worse off than they were before. They will become more confused in their mind or more indifferent in their will. Consequently, the preacher must do everything possible to make the issue plain, and then call the congregation to account. Eternal destinies are at stake.

Preaching that is dilatory about this fact has no evangelistic relevance. The Gospel does not permit us the luxury of indecision. The Son of God died for our sins, and whether we like it or not, we must answer for what we do with Christ. We cannot be neutral. For us to ignore the responsibility is to blaspheme God. It is the preacher's business to make people face this fact, and cause them to seek the Lord while He may be found.

For this reason, the appeal for commitment is the most decisive point of the message. The wise preacher, thus, should give as much or more consideration to the invitation as to any other part of the sermon. Like the rest of the discourse, it should be bathed in prayer. While meditating upon it, he or she can decide what will be expected and how to ask for it. Clarity here is essential. A preacher who ends up in confusion has lost the effect of all his labor. Sometimes the whole sermon might be woven around the invitation, but always it should be so constructed as to make the invitation compelling in logic and winsomeness. This is the crowning achievement of the message.

Every sermon should demand a verdict, but the method of asking for it may vary according to the particular circumstances. Sometimes preachers may feel led to give the appeal in such a way as to call for no immediate public response; for example, asking those present to join in a closing prayer of dedication while they bow in their pews. People might be told to go home and pray about what God would have them do, to write a card or letter telling of their decision made in private, or to visit personally in the office to talk it over.

Invitations of this kind are probably more appreciated when speaking to Christians on subjects related to growing in grace. They should normally be used sparingly when addressing hardened sinners in fields white unto harvest. Such appeals can cause indefiniteness and encourage postponement of a decision.

With invitations calling for a public response, one of the most popular methods is to invite people to record their decision by signing a written statement of faith on a specially prepared card. Sometimes the preacher might ask for a show of hands or call people to stand to indicate some resolution. Convicted persons may be asked to remain after a service for counsel. Some prefer to direct them to an inquiry room where they may receive further instruction.
