First Thessalonians, part 3, The Model Church

1 Thessalonians 1:5 says,

⁵ For our gospel did not come to you in word only, but also in power and in the Holy Spirit and with full conviction; just as you know what kind of men we proved to be among you for your sake.

Paul explains why he is confident that the Thessalonians are among God’s chosen people (v. 4). The gospel was not merely heard—it transformed them. It changed their lives and their entire outlook on life. In this case, they had been seeking God through Old Covenant Judaism, submitting themselves to a position of second-class citizenship in the Kingdom in order to know God through types and shadows.

New Covenant Transformation

Yet now they had heard Paul preaching the meat of the word (New Covenant antitypes), the good news that being “chosen” depended upon faith in Christ rather than physical genealogy. No doubt Paul had taught them Isaiah 56:6-8 and the meaning of “My house will be called a house of prayer for all the peoples.”

Perhaps also Paul taught them the law of equality in Numbers 15:15, 16,

¹⁵ As for the assembly [kahal], there shall be one statute for you and for the alien who sojourns with you, a perpetual statute throughout your generations; as you are, so shall the alien be before the Lord. ¹⁶ There is to be one law and one ordinance for you and for the alien who sojourns with you.

The Hebrew word kahal is translated in the New Testament Greek as ekklesia, “church.” Thus, ekklēsia did not originate as a uniquely Christian term; it was already the established Greek equivalent of kahal, the covenant assembly of God’s people. This passage is one of the clearest Pentateuchal affirmations of equal covenantal standing before the law for Israelites and believing resident aliens. Aliens living in Israel were required to be obedient to the law, and in turn, they were to be given equal standing before God.

Unfortunately, the Jews in the first century had long abandoned that understanding, thinking that their genealogical connection to Abraham gave them a closer relationship to God than any alien could ever match. Yet Moses warned them that if they followed other gods, God would cast them out of the land just as He had done with the Canaanites (Leviticus 18:24-28; 20:22-24; Deuteronomy 8:19, 20; 28:63-68).

The land itself was never an unconditional possession. Israel held it as God’s tenant. The same covenant standard applied to both the Canaanites and Israelites.

Likewise, Moses alluded to the New Covenant principle of the Holy Spirit circumcising the hearts and ears of the people (Deuteronomy 10:16; 30:6; Jeremiah 6:10, “their ear is uncircumcised”). Stephen told the unbelieving Jews in Acts 7:51,

⁵¹ You men who are stiff-necked and uncircumcised in heart and ears are always resisting the Holy Spirit.

In other words, they had failed to keep the law of Moses and did not believe the prophets. There is no doubt, then, that the Jews in the synagogue of Thessalonica had become incensed when Paul expounded upon these Scriptures on the third Sabbath.

The law and the prophets gave Paul the foundation of his teaching in Romans 2:29,

²⁹ He is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter.

Again, Paul writes in Philippians 3:3, “For we are the true circumcision, who worship in the Spirit of God.” Physical circumcision was the sign of the Old Covenant; Heart circumcision is the sign of the New Covenant. Both were intended to provide Covenantal Identity. However, just as the Old Covenant failed to bring righteousness, so also did physical circumcision fail to provide Covenantal Identity as God’s chosen ones. In other words, while men recognized a fleshly sign of such Identity, God examined the heart to see if it had been circumcised.

Hence, the meat of the word teaches the difference between the two covenants. This new understanding is the foundation of true Christianity. It is not a new teaching, nor does it put away the law or the prophets (Matthew 5:17); instead, it re-establishes the truth that both Moses and the prophets taught but which had been lost by the long-time traditions of men.

Four Characteristics of the Gospel

Paul tells the Thessalonian believers that the gospel was accompanied by four things:

1. Word – the objective proclamation of Christ.
2. Power – the gospel accomplished what mere human speech could never accomplish.
3. The Holy Spirit – the Spirit taught Truth, wrote the law on their hearts, changed their understanding of covenant theology, and produced new life.
4. Full conviction – the preachers proclaimed the gospel with certainty, the Spirit bore witness by His Power, and the hearers embraced it with assurance.

Paul then points to the integrity of his own life: “You know what kind of men we proved to be.” The credibility of the gospel was reinforced by the character of its messengers—in this case, Paul, Silvanus, and Timothy. Throughout Scripture, God not only sends a message but also forms messengers whose lives authenticate what they preach.

1 Thessalonians 1:6 says,

⁶ You also became imitators of us and of the Lord, having received the word in much tribulation with the joy of the Holy Spirit.

The Thessalonians imitated Paul because Paul himself imitated Christ. 1 Corinthians 11:1 says,

¹ Be imitators of me, just as I also am of Christ.

This imitation was not external ritual but a willingness to endure suffering for the sake of the gospel. Notice the remarkable combination in 1 Thessalonians 1:6, “much tribulation” and “joy of the Holy Spirit.” Normally suffering diminishes joy, but the Holy Spirit enables believers to rejoice even in persecution. This reflects Jesus' teaching in Matthew 5:11, 12,

¹¹ Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me. ¹² Rejoice and be glad….

The Christian life is therefore not the absence of suffering but the presence of divine joy in the midst of suffering.

A Model Church

1 Thessalonians 1:7 says,

⁷ So that you became an example to all the believers in Macedonia and in Achaia.

Apparently, this made front-page news. Their faith quickly became known throughout Greece. Instead of remaining immature converts, they became a model church. Paul had spent only a short time in Thessalonica, demonstrating that spiritual maturity depends less upon the length of instruction than upon the responsiveness of the heart.

Macedonia included cities such as Philippi, Berea, and Thessalonica itself. Achaia included Corinth and Athens. Their influence therefore extended throughout much of Greece.

1 Thessalonians 1:8 continues,

⁸ For the word of the Lord has sounded forth from you, not only in Macedonia and Achaia, but also in every place your faith toward God has gone forth, so that we have no need to say anything.

The expression “sounded forth” (Greek: exēchētai) literally describes a trumpet blast or the echo of a loud sound. The Thessalonian church became an echo chamber of the gospel. Their witness spread naturally through travel, commerce, and personal testimony.

Paul is not describing an organized missionary program so much as a congregation whose transformed lives proclaimed Christ wherever they went. Their reputation had preceded Paul. When he arrived elsewhere, people already knew about the remarkable conversion of the Thessalonians.

1 Thessalonians 1:9 says,

⁹ For they themselves report about us what kind of a reception we had with you, and how you turned to God from idols to serve a living and true God.

Most of the Thessalonian believers had been Gentiles. They abandoned the worship of dead images made by human hands. Throughout the Old Testament idols are repeatedly described as unable to see, hear, or speak (Psalm 115:4–8; Isaiah 44:9–20). Conversion required a complete break with their former religious loyalties.

Conversion is never merely turning away. It is turning toward someone. The word “serve” (douleuein) literally means to serve as a slave. They had exchanged slavery to idols for joyful service to God. Furthermore, they had been delivered from the slavery of the Old Covenant itself, which Paul explains in great detail in Galatians 4. He summarizes this in Galatians 5:1,

¹ It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery.

1 Thessalonians 1:10 concludes,

¹⁰ And to wait for His Son from heaven, whom He raised from the dead, that is Jesus, who rescues us from the wrath to come.

Paul completes his description of Christian conversion with a third element. Believers not only turned from idols to serve the living God, they also “wait for His Son from heaven.” The Christian life always possesses a future orientation, while living in the present. The verb translated “wait” (anamenein) occurs only here in the New Testament and denotes eager, expectant waiting.

The object of hope is not merely an event but a Person. While they had already experienced Christ on one level, they awaited a greater manifestation yet future. The believer looks back to his past and repents from idolatry. He then lives in the present, while serving the true and living God. This is discipleship.

Finally, he waits for God’s Son from heaven. This is hope. Thus, the Christian life encompasses past, present, and future.
