A quick story...
A number of years ago, my best friend passed away at the age of 30. He had many friends as he was probably the most well liked christian man I've ever met.
A couple days before his funeral, I was working in my paint booth when God's voice came to me and said, 'Call Lloyd'. The only Lloyd I knew I had met about 7 years prior when my friend had introduced me to him, and I didn't know where he worked or what his last name was.
I walked out of the booth up to my desk and asked God where he worked. God gave me the name of a heavy equipment dealer in town so I called and asked if there was a 'Lloyd' that worked there. She said 'hold please'.
Lloyd answered and I asked if he knew a man named, ______? He said 'Yes I do'.
I told him about the accident and when the funeral was. He shared that he and my friend had been planning on starting a business together and he couldn't understand why my friend wasn't getting back to him.
Lloyd was able to attend the funeral that he otherwise would've missed.
God showed me that day that we are like children before him. When I ask my children to get ready because we're leaving sometimes they ask 'Where?, Why? etc. and I'll tell them 'just get ready'. It is a joy when my children just respond in obedience and get ready to go without all the questions.
That's how it is with God. We are on a 'need to know' basis sometimes (actually a lot of times) and we should listen and trust.
God knows far more than we do. It's for our own good and the good of who knows who else?
