The Church's One Foundation

Jesus Christ is the one and only foundation of the Church. With our lives we build upon this foundation. If we do things that will last for eternity (obey God, witness to others, etc.) these are like gold, silver, and precious stones that will last into eternity. But if we live for our own comfort and pleasure in this life (hay, wood, and stubble) we will still be saved but there will be nothing left of our life's work.
