Nothing in this world serves a central role in ensuring the effective functioning of any institution as compared to communication. Be it a government, Non-Governmental, a family, a school or a criminal institution, communication is the most essential part of its effort to remain intact. In fact, communication could be compared to blood veins in the body of the institution. Should the blood veins fail to reach a certain body part, the part will not be accessible to essential nutrients including water and oxygen leading to its malfunctioning or death. This is exactly the role of communication in the body of any institution. Failure of any part of the institution to get access to the essential information circulated by communication leads to the malfunctioning of that part. Unfortunately, when one part dies, the effect is felt by the whole body. With such importance tugged to it, it is therefore important that an institution gives great priority to communication. This paper will therefore try to highlight the principles of communication and also point out how different factors within a communication environment can affect interpersonal communication. In addition, the paper will put the factors in real life experience by identifying its implication in the preaching of the gospel of Christ. Principles of Communication Unlike the normal perception of people, communication is more than just the words and the message that passes from one person to the other. Several other things play a role in ensuring that the message reaches the intended person and with the intended meaning. Without considering these several facets of communication, the chances that the message will not serve the intended function are high. In the face of preaching the gospel of Christ, using the words from the bible alone can fail to be effective if other factors of communication are not considered. With other factors not being considered, the chances of winning souls to Christ will not be achieved. What, therefore, are the principles of communication? To understand the principles of communication, the use of communication models will be essential and will assist in better understanding. Therefore are several models of communication developed by different scholars in the field of communication (McCloskey, 2006). In this paper, we shall use the Basic Communication Model and the Shannon-Weaver Model. These two models will give us an insight in the principle factors of communication and offer an explanation through which these factors influence communication. The Basic Communication Model (McCloskey, 2006). The Shannon-Weaver Communication Model (McCloskey, 2006). From the models above, several factors can be found to play different but important roles in communication. These are the principles of communication (McCloskey, 2006). Information Source This is the person from which the message originates. This person wants a certain message to reach the desired recipient and make him respond in the desired way. In the gospel realm, this involves the pastor or the evangelist who is preaching the word to the nonbelievers. He is transmitting the message with the sole aim of winning their souls to Christ. Encoding This is a process carried out by the source. It involves the putting of the message in a coded system before transmitting it to the respondent. In this process, the coded system includes words that could be spoken or written. It can also include other forms of communication systems including gestures and facial expressions. The source should always ensure that the respondent is in a position to understand the coded system used otherwise the communication process will not send the desired message leading to lack of communication. In this stage of communication, the preacher must ensure that his message of Christ is put in such a way that it will be influential to the nonbeliever. The source of the message should package his message in a very appropriate way that will consider the listener and his attitude and assumptions. The Message This is the specific content of what the source is transmitting to the respondent. For example, if a preacher is speaking to a congregation, the content of the message will be Jesus Christ and his forgiveness of sin and that he died and was resurrected on the third day. Noise Source These are the signals that are unwanted that and which serve as disruptors of the fidelity of the message. Several factors act as sources of noise when it comes to interpersonal communication. These include Cultural noise, which involves the cultural factor
