There are many good uses of nails, like fastening materials together , house, table , chairs etc. But we also have to watch out for loose nails, they are dangerous specially for young children, for vehicle tires. Through the years I have accumulated nails, I do not want to throw them away but I need to store them safely .
Nails in the wrong place like tires or puncturing our skin can be worrisome like sin in our lives. Evil men nailed Jesus to the cross and God allowed it and used it to purchase our salvation.
I believe the lesson here is if we are experiencing pain or hardships in our lives, losing hope in some cases the answer is we need to remember to look to Jesus who experienced pain and death for us.
Let us have Jesus every moment in our lives, in joy and in pain.
