Delete specific paragraphs based on substring using word macro

I need a MS Word Macro that would search for a specific substring in every paragraph throughout the document and delete paragraphs that don't contain that string.

I tried this macro code:

VB

Sub DeleteParagraphContainingString()

       Dim search As String
       search = "delete me"

       Dim para As Paragraph
       For Each para In ActiveDocument.Paragraphs

           Dim txt As String
           txt = para.Range.Text

           If Not InStr(LCase(txt), search) Then
               para.Range.Delete
           End If

       Next

   End Sub

But it deletes all the paragraph though it has that subtring. I don't have any clue where is the wrong in the code.

Steps to do:

Loop through the collection of paragraphs
Check if paragraph contains searched string

if contains, skip to next paragraph
if not, delete

Sample code:

VB

Option Explicit

Sub SearchAndDestroy()
Dim p As Paragraph
Dim searchedText As String

On Error GoTo Err_SearchAndDestroy

searchedText = "Delete me"
For Each p In ThisDocument.Paragraphs
    If InStr(1, p.Range.Text, searchedText, vbBinaryCompare) > 0 Then GoTo SkipNext
    p.Range.Delete Unit:=wdParagraph, Count:=1
SkipNext:
Next

Exit_SearchAndDestroy:
    Exit Sub

Err_SearchAndDestroy:
    MsgBox Err.Description, vbExclamation, Err.Number
    Resume Exit_SearchAndDestroy
End Sub
