God through His apostle Paul reveals the nature of the church in this inspired book, the book of Ephesians, from His Holy inspired, infallible, inerrant Word, the Bible. The nature of the true church of God finds its source in Jesus Christ and what He has done for His children. The genuine church of Jesus Christ is made up of redeemed Jews and Gentiles.
11 Therefore remember that you, once Gentiles in the flesh—who are called Uncircumcision by what is called the Circumcision made in the flesh by hands—12 that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. 14 For He Himself is our peace, who has made both one, and has broken down the middle wall of separation, 15 having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace, 16 and that He might reconcile them both to God in one body through the cross, thereby putting to death the enmity. Ephesians 2:11-16
Paul reminds the Gentiles that though they were aliens from the commonwealth of Israel and strangers to the covenants of promise, Jesus Christ has brought them near to God through His blood. Even more, through His death upon the cross for all of mankind, Jesus Christ has reconciled both Jew and Gentile to God. He has made one people for God from the two, who were formerly alienated from one another through the law of commandments, because He put to death that enmity between Jews and Gentiles which existed through the law of commandments contained in ordinances. The law was nailed to the cross when Jesus Christ was crucified because the law is against both Jew and Gentile; through the law comes the knowledge of sin, and every human is found guilty in God’s sight.
14 …having wiped out the handwriting of requirements that was against us, which was contrary to us. And He has taken it out of the way, having nailed it to the cross. Colossians 2:14
19 Now we know that whatever the law says, it says to those who are under the law, that every mouth may be stopped, and all the world may become guilty before God. 20 Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin. 21 But now the righteousness of God apart from the law is revealed, being witnessed by the Law and the Prophets, 22 even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference; 23 for all have sinned and fall short of the glory of God, 24 being justified freely by His grace through the redemption that is in Christ Jesus, 25 whom God set forth as a propitiation by His blood, through faith, to demonstrate His righteousness, because in His forbearance God had passed over the sins that were previously committed, to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus. Romans 3:19-26
Jesus Christ has made one body of believers through reconciling the two together to God and to one another. What the law could not do for the Jew, and what the law cannot do for the Gentile, Jesus Christ did for us all, making us righteous in God’s sight through repentant faith in Him. Jesus Christ became our propitiation through His blood that we might be justified in God’s sight, declared not guilty, and become the righteousness of God through Him.
17 And He came and preached peace to you who were afar off and to those who were near. 18 For through Him we both have access by one Spirit to the Father. 19 Now, therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, 21 in whom the whole building, being fitted together, grows into a holy temple in the Lord, 22 in whom the whole building, being built together for a dwelling place of God in the Spirit. Ephesians 2:17-22
Through Jesus Christ, both Jew and Gentile are at peace with God and have access to God the Father by the Holy Spirit. Gentiles are fellow citizens with the saints, members of the household of God through the Word preached by the apostles and prophets, preaching and teaching about Jesus Christ. The body of believers is built upon the foundation of the Word of God which bears witness to Jesus Christ in both the Old Testament, the Law and the Prophets, and the New Testament, the foundation of the apostles and prophets. The whole of the Bible is about Jesus Christ, from beginning to end, and tells about His wonderful plan of salvation, His death upon the cross for our sins and His resurrection from the dead for our justification. All who repent of their sin, whether Jew or Gentile, and put their faith in Jesus Christ are born again, they become members of Christ’s body. We are His body, His building, His church, in whom God dwells through His Holy Spirit.
13 For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. 1 Corinthians 12:13
Lord Jesus Christ, we are Your redeemed beloved saints. May we live for Your glory, praise and honor. Thank You that You have made us Your beloved possession through Your gracious work for us on the cross. Thank you Heavenly Father for Your most gracious gift. Amen!
