Can you learn how to do things by reading the manual?
I remember one of the hardest things I ever learned to do was set my old VCR to record a show. I read the manual and reread the manual and still the shows did not record. Until someone showed me how to do it.
I remember driving my first big commercial vehicle and the instructor telling me that when I shut 'er down I needed to pull the engine kill. But when the time came to shut 'er down, I put it in the proper gear, set the brake, turned the key off and pulled the key out. The engine was still running. Someone had to come show me where the engine kill switch was.
It is easy to get dismayed (lose your courage or become disappointed) when you are unsure of yourself.
Whether giving a speech in High School or trying new machines at the gym and even using the self checkout at the grocery, it is ALWAYS easier if someone else goes ahead of you.
God tells us in His Word that He will go ahead of us. We just have to keep our eyes on Him and follow His lead.
The Lord is the one who goes ahead of you; He will be with you. He will not fail you or forsake you. Do not fear or be dismayed." (Deuteronomy 31:8 NASB)
