Tomorrow I'll be preaching about the primary metaphor that the Bible uses to describe the church - The Body of Christ.
There are so many insightful Scriptures that we won't have time to study them all, so I've pasted a number of these below. It might be a good study to read through them and contemplate on how the church is supposed to be the Body. (Note, we'll be covering I Cor. 12, Eph 4 and Rom. 12 tomorrow).

Rom 7:4-5
4 So, my brothers, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit to God.

1 Cor 10:14-24
14 Therefore, my dear friends, flee from idolatry. 15 I speak to sensible people; judge for yourselves what I say. 16 Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? 17 Because there is one loaf, we, who are many, are one body, for we all partake of the one loaf.

24 Nobody should seek his own good, but the good of others.

1 Cor 11:23-26
23 For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, 24 and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me." 25 In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me." 26 For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes.

Eph 1:22-23
22 And God placed all things under his feet and appointed him to be head over everything for the church, 23 which is his body, the fullness of him who fills everything in every way.

Col 1:18
18 And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy.

Col 1:24
24 Now I rejoice in what was suffered for you, and I fill up in my flesh what is still lacking in regard to Christ's afflictions, for the sake of his body, which is the church.

Col 2:18-19
18 Do not let anyone who delights in false humility and the worship of angels disqualify you for the prize. Such a person goes into great detail about what he has seen, and his unspiritual mind puffs him up with idle notions. 19 He has lost connection with the Head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.

Col 3:15-17
15 Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful. 16 Let the word of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns and spiritual songs with gratitude in your hearts to God. 17 And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him.
