Excel VBA - Search through list and pop-up message - excel

Question

I would like to ask for some help regarding the following problem:
I have a workbook with two sheets. Sheet 2 contains 2 lists with phrases in them and Sheet 1 has some data. I want to create a macro that checks the data in Sheet 1 and if it finds a phrase that does not appear in the lists in Sheet 2 it gives a pop-up message. Furthermore, Sheet 1 will contain phrases separated by commas. Is it possible to also check that as well? (see screenshot)
Although really simple, I have worked out the following, however, I am sure the answer is more complicated.
Any help is appreciated!
Thank you in advance!
My code:
Sub check()
For i = 2 To 2
If Cells(i, "A") <> Worksheets("Sheet2").Cells(i, "B") Then
MsgBox "Phrase 1 does not match"
End If
For j = 2 To 2
If Cells(j, "B") <> Worksheets("Sheet2").Cells(j, "C") Then
MsgBox "Phrase 2 does not match"
End If
Next j
Next i
End Sub

The VBA code should look like this
For all cells in column 'Phase 1'
Use the SPLIT() function to split the comma separated values
and store them into a list of distinct values
For all distinct values in the list
Use the VLOOKUP function on the 'Phrase list 1' column in sheet2,
searching for the current value
If vlookup returns a valid result then
do nothing
else
pop up message
end if
end loop of distinct values
end loop of cells in column 'Phase 1'
