When I look at these rusty, old weather torn iron nails I think of the nails that pierced Christ's hands and feet that nailed him to the cross to be crucified for our sins. These nails are heavy and could easily go right through someones flesh as they are heavy, hard and unforgiving. I think of the cruel nails and the cruel cross and what an agonizing way to die but Christ choose freely to take on this task for us so that we may not suffer the same fate. It is His blood that covers our sins and by His stripes, we are healed.
