1 Corinthians 3:

(the Apostle Paul wrote:)
11 And no one can ever lay any other real foundation
than that one we already have - Jesus Christ.

Matthew 7:

(Jesus says:)
24 "All who listen to my instructions and follow them are wise,
like a man who builds his house on solid rock.
25 Though the rain comes in torrents,
and the floods rise and the storm winds beat against his house,
it won't collapse, for it is built on rock.
26 "But those who hear my instructions and ignore them are foolish,
like a man who builds his house on sand.
27 For when the rains and floods come,
and storm winds beat against his house,
it will fall with a mighty crash."
(Living Bible)
