The Foundation is always the same, God Himself has laid it: and it is Jesus Christ Himself.
But the building differs according to the difference in materials and workmanship.
There is no building except Christ be the Foundation; yet many of God’s servants use wood, hay and stubble, while some use gold, silver and precious stones.
God does NOT and will NOT ask how large a building you have built, or how clever or speedy or ornate you built it;
Instead, He asks what materials you have used.
