Using Currentcell.offset To Copy A Cell From Two Variables

I have a spreadsheet with 2 worksheets. I have a variable cell and a display cell on Worksheet A and two other cells with information on Worksheet B that I need copied over to Worksheet A based on what is entered for the variable on Worksheet A.

I want to be able to enter a variable in Worksheet A, cell B25. I then want the code to look up the variable I just entered at B25 on Worksheet B, column A. Once the code finds the variable, then I want the code to copy what is in column B and enter it into Worksheet A cell C25.

In other terms, I want to enter "Bob" in Worsheet A, B25. On Worksheet B, I have 50 different names of people in column A and additional info directly to the right of their names in column B. When I enter "Bob", I want the code to find "Bob" on the Worksheet B and enter "is worthless" on Worksheet A, cell C25.

I have tried and got the code to work with several If/then statements and I accomplished the same using a select case arguement as well using something along the lines of "if B25="Bob" then C25=worksheet B("B2")" assuming Bob is in cell A2. My concern is the info on Worksheet B is fluid. I need to be able to sort and add additional lines at any given time. My data set is going to be between 500 and 800 rows. Any time I add a row and re-sort the data set, I want the code to find "Bob" in column A and then display what is in column B in Worksheet A, C25. I can continue to use the if/then statements, but they are static and if I add a new row near the top, I would have to re-number all the if/then statments in the code.
