Hebrews 2:18
"For in that he himself hath suffered being tempted, he is able to succour them that are tempted."
When you need someone to work on something that is broken, you want a qualified technician who knows what they are doing. When I go to get my car worked on, I look for the badge on the mechanic's uniform that shows they are a qualified technician. Why do we look for someone who is a qualified technician? Because we want someone who has been trained to deal with our problems because they will know best how to fix and repair what is wrong.
