And the apostles gathered themselves together unto Jesus, and told him all things, both what they had done, and what they had taught. - Mark 6:30
The Church:- S.C. 1577 'ekklesia': literally, a calling out [out from the origin]; secularly, an assembly of citizens (Acts 19: 32, 39,41);
in Greek O.T. [Septuagint] the congregation of Israel, as in Acts 7:38 the 'congregation' in the wilderness; the Christian community of saints on earth or in heaven or both.
Heb.2:12 [quoting from Ps.22:22] "...I will declare Your name to My brethren; in the midst of the assembly I will sing praise to You." The writer to the Hebrews attributes this saying to the Lord Jesus, who calls the members of the church, "My brethren," and says He "will sing praise to You, [Yahweh] in the midst of the assembly, [church]".
The church are the called out ones, those who have been predestined to be conformed to the image of the Son, called, justified and glorified, Rom.8:29-30. The church are those who do not stumble at His hard sayings (Jn.6:60), who know that eternal life is only found in the words of the Lord Jesus, (Jn.6:68).
Jn.5:24 "Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgement, but has passed from death into life."
In Matt.16:18 we have the first mention of the word 'church' [ekklesia]. "And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it."
Jesus commits to "building the church". He proclaims it will withstand the gates of hell. It will be built in the foundation of faith in Him: "Thou art the Messiah, the Son of God." Mt.16:16-17. This can only be known by a revelation from God, bringing faith to the believer.
Jesus is the "petra" rock on which the church is built.
1 Cor.10:4 "...all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ."
Matt.7:24-27 "Therefore whoever hears these sayings of mind and does them, I will liken him to a wise man who built his house on the rock: and the rain descended, the floods came, and it did not fall, for it was founded on the rock. But everyone who hears these sayings of Mine, and does not do them, will be like a foolish man who built his house on the sand: and the rain descended, the floods came, and winds blew and beat on that house; and it fell. And great was it's fall."
The church is the congregation of the Lord Jesus. The Lord Jesus is the builder of the church. He is the foundation, the tried stone, the precious cornerstone, a sure foundation. Isa.28:16 "Therefore thus says the Lord God: 'Behold, I lay in Zion a stone for a foundation, a tried stone, a precious cornerstone, a sure foundation,'"
Ps.118:22-23 "The stone which the builders rejected has become the chief cornerstone. This was the LORD's doing; it is marvelous in our eyes." [quoted in 1Pet.2:7].
He is the apostle "who was faithful to Him who appointed Him," [Heb.3:2]. Jesus the Messiah is the builder of God's house, the church. Heb.3:3 "For this One has been counted worthy of more glory than Moses, inasmuch as He who built the house has more honor than the house." He is the Son over His house, "whose house we are," v.6.
The same one who laid the foundation of the house of God will also finish it. Zech.4:9 "The hands of Zerubbabel have laid the foundation of this temple; his hands shall also finish it." Zerubbabel is a type of Christ, used by God to rebuild the temple in Jerusalem after the Babylonian exile. This verse speaks prophetically of Jesus, as the apostle of God, building the church.
Peter is the "petros" stone, who will be a foundation stone as an apostle. The church is built by Jesus on the foundation ministries of apostles and prophets which He has set in the church. Eph.2:20 "having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone."
Every believer is called a living stone and is being built into the house of God, the church.
1Pet.2:5 "you also, as living stones, are being built up a spiritual house, a holy priesthood to offer up spiritual sacrifices acceptable to God through Jesus Christ."
In Matt.16:19 Jesus gives to Peter, a foundation apostle, the keys of the kingdom of heaven, "And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." Keys open doors that are locked; they also represent authority.
