What Foundation do You Stand on Today? Rock or Sand?

I absolutely love this worship song!!   On Christ the Rock I stand, no double minded shifting sand.  On Christ the rock I plant my feet, a firm foundation for me!!  When we stand on a firm foundation, nothing can move us!! We are His and He is ours!!  Oh yeah, the adversary will try.  That's his job.  But nothing can harm or move us because we are his Sons/Daughters.  Praying you will be encouraged today through this song!! We serve one Holy God!  Bless you in your coming and going today!!!
