<p>3:12 <i>But if anyone builds on the foundation gold, silver, costly stones, wood, hay, stubble</i>- The builders upon the foundation of Paul's basic preaching work were those who then did the pastoral work of teaching all that the Lord has commanded (Mt. 28:20). The materials they build with refer to the quality of those they build up. Gold, silver and precious stones can pass through the fire (:13)- the final test of judgment day. And these three figures are used elsewhere about the believers. The other corresponding three figures will be burnt up by the fire. Here we see the principle that the final acceptance of individuals is partly related to the quality of the teaching and caring work done for them by third parties. God has built this factor into the algorithm of our salvation in order that we may each one devote ourselves to caring for others spiritually, and so that likewise we may realize our own need for others' help in our own path to salvation.</p>
