The believer’s responsibility in evangelism
As ambassadors for Christ [cf. II Cor. 5:20], what are believers to do in order to be faithful to our Lord in regards to evangelism? Two considerations in particular come to mind:
A. We must present all the propositional truths of concerning the Gospel, not holding anything back simply because it may be deemed offensive (i.e., the sinners’ guilt or the blood of Christ).
B. We must serve God with all our heart and soul as well as our mind and strength in evangelism: Acts 20:31
God has appointed not only the what of the Gospel (the facts about the life, death, burial and resurrection of Jesus according to the Scripture), but He has also appointed the how of the Gospel (the way that we present the Good News of Jesus Christ). So while our presentation of the Gospel must certainly contain the facts of the Gospel and therefore based on objective truth, we must also present the Gospel with what I have termed "total communication;" that is, the Gospel must be reflected in the way that we live our lives, in the seriousness of our demeanor- especially when discussing spiritual matters- and in the passionate urgency by which we call sinners to repentance and faith.
That prince of doctrinally sound Gospel-centered preachers, Charles H. Spurgeon, illustrates this principle of "total communication" wonderfully in his classic work on evangelism, The Soul Winner:
I have heard of a man who was dying, and he sent for the minister to come and see him. When the minister came in, the dying man said to him, "Do you remember a young man walking with you one evening, some years ago, when you were going out to preach?" He said, he did not. "I recollect it very well," replied the other. "Do you not remember preaching at such-and-such a village, from such-and-such a text, and after the service a young man walked home with you?" "Oh, yes, I remember that very well!" "Well, I am the young man who walked home with you that night; I remember your sermon, I shall never forget it." "Thank God for that," said the preacher. "No," answered the dying man, "you will not thank God when you have heard all I have to say. I walked with you to the village, but you did not say much to me on the way there, for you were thinking over your sermon; you deeply impressed me while you were preaching, and I was led to think about giving my heart to Christ. I wanted to speak to you about my soul on the way home; but the moment you got out you cracked a joke, and all the way back you made such fun upon serious subjects, that I could not say anything about what I felt, and it thoroughly disgusted me with religion, and all who professed it, and now I am going to be damned, and my blood will lie at your door, as sure as you are alive:" and so he passed out of the world. One would not like anything of that sort to happen to himself; therefore, take heed, brethren, that you give no occasion for it. There must be a prevailing seriousness about our whole lives, otherwise we cannot hope to lead other men to Christ.Christians reading this post: We are responsible to speak God's truth holding nothing back either in terms of the Gospel content we proclaim or in terms of our own heart-dedication to the truth of the Gospel. I plead with you to examine yourself in this area, that we may all soberly evaluate ourselves to see if we are faithful to our Lord in evangelism.
