Summary: The Study Of The Work Of The Church

The Study Of The Work Of The Church

Mark 16:15 (KJV)

15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.

Why does the church exist? What is the purpose of it? What is its work? To find out, we will go to God's Word.

First of all, let us observe that the church is not to be in secular business. It is not to run hospitals or to publish books for the purpose of making money. These things may be good. Individual Christians certainly have the right to do them. However it is simply not the work of the church. More and more the religious world has come to such activities.

They are just taking another step away from God's purpose for His people.

Through God's Word, we will find that the work of the church is threefold:

1. Preaching the Gospel,

2. Helping those in need, and

3. Edifying the church.

Let's notice them one by one:


Christ taught the apostles, just after His resurrection and just before His ascension to heaven, "Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age. Amen" (Matthew 28:19-20). "And He said to them, 'Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned'" (Mark 16:15-16). Later, Paul told young Timothy, "Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching" (2 Timothy 4:2). Other verses could be given. These show clearly the Lord's desire for the Gospel to be taught.

Now what did the church do in the days of the apostles? The members did what the Lord asked them to do. They preached the Word. The book of Acts is full of examples of this. In all of the cases of conversion, a preacher was on hand to teach the Will of the Lord. Read Acts 2, Acts 8, 9, 10, and Acts 16. But who did the preaching and teaching? After a great persecution came upon the Lord's people in Jerusalem, the record says, "Therefore those who were scattered went everywhere preaching the word" (Acts 8:4). Next, what did they preach? All you have to do is to read the cases of conversion in the book of Acts. You will see for yourself. But briefly, they taught:

1. Christ was the Son of God,

2. what one should do to be saved,

3. the importance of the church,

4. the items of worship,

5. the importance of the Christian's life, etc.

Paul summed it up by saying, "For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God" (1 Corinthians 1:18).

Beside the fact that the Lord commanded that His Word be preached, Paul says that faith comes by hearing the Word of God (Romans 10:17). Again Christ said, "And you shall know the truth, and the truth shall make you free" (John 8:32). Again, "How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher" (Romans 10:14)? All of this is to say that a man is lost (Romans 3:23; Romans 6:23). The love of God must be preached (Romans 5:8). It shows that man has a Savior (John 3:16). Through obedience to God, man can be saved from his sins (Romans 1:16-17; Mark 16:15-16). Those who are ignorant of God's will or who do not obey it, will be lost (2 Thessalonians 1:7-9). Thus, God's Word must be preached.


The Bible shows us that the church was concerned about those who were in need of help. They were helped as there were means to do so. In Acts 2:45, we read, "and sold their possessions and goods, and divided them among all, as anyone had need." This was on a free will basis, of course. But, again, in Acts 6, we read of an argument that came about between the Grecians and Hebrews. The Grecian widows were neglected in their daily care. The apostles called the disciples together. They had them to choose seven men from among them. They were appointed to handle this part of the work of the church.

We read of Paul going to Jerusalem to help the poor saints there. He goes on to say, "But now I am going to Jerusalem to minister to the saints. For it pleased those from Macedonia and Achaia to make a certain contribution for the poor among the saints who are in Jerusalem" (Romans 15:25-26). So Paul writes to the brethren at Corinth, "Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also: On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come" (1 Corinthians 16:1-2).
