The Mission of the Church
Preached at Wayside PCA, Homecoming, October 14, 2007

We DO have a mission! Over the years, the mission of the church has become unclear to many, and today I would like to clarify.

THE MISSION OF THE CHURCH is to build the Kingdom of Jesus Christ.

We do many other good and wonderful things, important things: we feed the poor, we build hospitals, we visit the sick and widows and orphans, we teach English to immigrants, we establish preschools and colleges, and so on. But all of these things MUST NEVER BE DONE AS ENDS IN AND OF THEMSELVES. The purpose of all these must be to build up the Kingdom.

Defining terms: What is the "Kingdom" of Jesus Christ?

The Kingdom is the area over which the King has authority.

Therefore, the Kingdom of Christ can and does mean a number of different things.

1) The entire universe is the Kingdom of Christ, including all the earthly nations. Daniel 4:34-37

2) The Old Testament nation of Israel was the Kingdom of Christ. Theologians sometimes call Israel the "Theocratic Kingdom."

3) The New Testament form of the Church is the Kingdom of Christ (I Peter 2:4-10).

Christ is the Head of the Church. Christ is the Rock of Daniel that struck the Roman empire, and which is now growing and filling the earth. Jesus said the Kingdom would be like a mustard seed, or like leaven. (Matt. 13:31-33)

4) The future fullness of the Kingdom spoken of in Revelation 11:15-19...

The mission of the Church is building the Kingdom of Christ, and we do that in three different ways:

Note: Jesus said "I will build my church..." We recognize always that we have power only as we work together with Jesus Christ. He is the vine, we are the branches. We must remain in Him to bear fruit. He must direct our work, and send the Holy Spirit to empower our work. We are "laborers together with Him."

I. We build the Kingdom by preaching the Gospel and winning people to faith in Christ.

Mark 16:15

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

Note well: They say "charity begins at home." It is certainly true that "evangelism must begin at home."

Deuteronomy 6:6-9 says:

Who will evangelize your children? Who will teach them Bible knowledge? Who will speak to them of Christian character and living like Christians in the world? Who will give your children a Christian world view? Don't rely on even Sunday School teachers, and certainly don't rely on the public school to do the job for you. Parents, it is up to YOU to do all these things, and God says that plainly.

Matthew 28:18-19

Every skyscraper goes up one piece at a time. But in the end is a very large building. People come to Christ one person at a time, but when enough people turn to Christ, the nation becomes a Christian nation. Let us not be satisfied with 10% of our population. We must plead with God in prayer to turn the hearts of Americans to Christ. Our present percentage is too small to have much of an effect on morality and law. Pray! It is God that can bring revival, and no one else can do it.

Acts 1:8

8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."

And people from every tribe and tongue will come to Christ. See Revelation 5:9-10...

II. We build the Kingdom by establishing and strengthening churches.

There are many people who drop out of church, and see nothing wrong with that. Obviously they don't read their Bibles, or they don't care what the Bible says...

2 Co 11:27-28

Why did the Apostle Paul suffer so much? Why was Paul so in earnest with the Ephesian elders?

Acts 20:25-31

Why did Paul leave Titus in Crete to ordain elders in all the churches? Titus 1:4-5

Ephesians 4:11-16 Who gave church officers: Apostles, evangelists, teachers etc to the Church?

Do you think Jesus was just kidding around when He established a VISIBLE church body with officers? May we just ignore His will and get away with that?

Hebrews 10:25 Is it OK for Christians to ignore this verse?

25 Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another—and all the more as you see the Day approaching.

Hebrews 13:17

17 Obey your leaders and submit to their authority. They keep watch over you as men who must give an account. Obey them so that their work will be a joy, not a burden, for that would be of no advantage to you.

NOTE: Christ wants every Christian to do two things: 1) Grow. 2) Help your brothers/sisters to grow. You can't grow all by yourself. An ember removed from the fire goes out. We are each of us responsible to live together with other Christians, to allow them to influence us, and to influence them in our turn.

III. We build the Kingdom by being salt and light in the earth.

America needs a big dose of salt, and a giant spotlight. Saturday's newpaper had a lengthy article showing that the average American knows the recipe for a big mag better than he/she knows the 10 commandments. Why is that true? Because MacDonalds spends billions on advertising, and because we won't take the time to teach the Bible to our kids and to ourselves. Can YOU name the 10 commandments in order? (Exodus 20) Let's try:

Matt 5:13-16

Colossians 4:5-6

2 Cor. 10:3-5

We ARE IN A WAR. Are you convinced? Are you willing to do battle? Can you wield the sword of the Spirit (the Word of God) to demolish arguments and pretensions?

Paul is our example (see Acts 18:1-5; Acts 26:24-29)

We may not have Paul's abilities and gifts, but we have the same mission: to be salt and light as we have opportunity.

Conclusion: The mission of the Church; our mission, is to build the Kingdom of Christ. We do that in three ways:
