Only those who are the “called out ones,” as the Greek word implies, are a part of that church. (Called out of the world purified and cleansed by His blood to be His own.)
It is the Lord that adds people, and saves them, to the church (Acts 2:47).
The church is more than an organization; it is a living, body, because Christ is within it.
Each member is a important part of the Churchs function. “For as the body is one, and has many members, and all the members are one in Him, being many, are one body: so also is Christ.” Read 1 Corinthians 12:13-31. An individual Christian cannot be a church but is to function as a member of the body, Christs body, His church. God set in the church various gifts, of and directed by the Spirit, in the word.
“It is a good thing to give thanks unto the Lord, and to sing praises unto thy name, O most High: 2. To show forth thy lovingkindness in the morning, and thy faithfulness every night,”
The Bible teaches us that as a body of believers we should be Thankful
“And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful.”
In good times an bad time we should always give thanks.
“Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ;”
We should thank him with words that are spoken.
“By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name.”
Ben Franklin, Told this story from New England history. “That in a time of great despondency among the first settlers of New England, it was purposed at one of there public assemblies to proclaim a fast. An old farmer arose, spoke of their provoking heaven with their complaints, reviewed their mercies, showed that they had much to be thankful for, and moved that, instead of appointing a day of fasting, they should appoint a day of thanksgiving. This was accordingly done, and the custom has been continued ever since.”
In spite of troubles and trails, lets us continually thank and praise Him.
