According to the grace of God given to me, like a skilled master builder I laid a foundation, and someone else is building on it. Each builder must choose with care how to build on it. For no one can lay any foundation other than the one that has been laid; that foundation is Jesus Christ. Now if anyone builds on the foundation with gold, silver, precious stones, wood, hay, straw—the work of each builder will become visible, for the Day will disclose it, because it will be revealed with fire, and the fire will test what sort of work each has done. If what has been built on the foundation survives, the builder will receive a reward. If the work is burned up, the builder will suffer loss; the builder will be saved, but only as through fire. Do you not know that you are God’s temple and that God’s Spirit dwells in you? If anyone destroys God’s temple, God will destroy that person. For God’s temple is holy, and you are that temple. Do not deceive yourselves. If you think that you are wise in this age, you should become fools so that you may become wise. For the wisdom of this world is foolishness with God. For it is written, “He catches the wise in their craftiness,” and again, “The Lord knows the thoughts of the wise, that they are futile.” So let no one boast about human leaders. For all things are yours, whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all belong to you, and you belong to Christ, and Christ belongs to God. (1 Corinthians 3:10-23, NRSV)
Everyone who adds to the church builds on what those before have built, but all of it is built on the foundation laid in Jesus Christ.
And anyone who tries to destroy the church, God will destroy that person.
We all belong to Christ and Christ belongs to God, and what we build should be built for God.
So add to the church, by living on the foundation of Jesus.
