I Corinthians 3:11-13 (NASB)
For no man can lay a foundation other than the one which is laid, which is Jesus Christ. Now if any man builds on the foundation with gold, silver, precious stones, wood, hay, straw, each man’s work will become evident; for the day will show it because it is to be revealed with fire, and the fire itself will test the quality of each man’s work.
We all have jobs to do in the Kingdom of God. Some plant, some water, as Paul discusses in chapter 3 of I Corinthians. No one's job is more important than the next person's. The important thing is that we all do our part, so that God will be glorified. The problems that Paul is addressing here are similar to what we see today in our churches.
We are squabbling over petty issues while the greater work is being neglected. The layers that we are adding to the foundation are shoddy, half-hearted, and messy. We are not getting away with the garbage that we are peddling among God's people. Our deeds and our motives will be revealed with tests and trials. The fire will prove the quality of our work, according to the Bible.
We must seek to please God in all that we do. If our lives are in sync with the Word of God, the fire will only prove it, not destroy it. Jesus Christ is the one true foundation. ANYTHING we build on that foundation must be worthy work, or it will burn away. Worthy work is Kingdom work (and everything necessary to perform Kingdom work). Whatever part you play, you have a responsibility to be the best God made you to be.
