Rock
‘He is the Rock at the bottom’ —> the ‘Cornerstone’ whom the builders have rejected:
“This (Jesus is the) Stone rejected by you the builders, but it has been made the Cornerstone.” (Acts 4:11)
P/S:
Rock on!
Remember, He is the Rock higher ‘than I’:
“From the end of the earth I call to You when my heart is faint; Lead me to the Rock that is higher than I.” (Psalm 61:2)
