The footsteps of great men have lead the way and we are left alone to follow them. Some have left prints so deep in the sand that they look like mini lakes to those of us standing on the shore and looking forward. How can anyone possibly fill the shoes that left steps imprinted so deep?
The answer is, no one can. Great men never intended for someone to walk directly in their footsteps. They merely hoped that by leaving a mark behind, others may head in the same direction and forge their own paths somewhat parallel.
This does not mean great men never had faults, doubts, or struggles. It just means even when they were brought to their knees they still moved forward. Grief can be strong enough, even for a stranger, that it may feel as if your feet were cut from underneath you. Keep moving forward anyway. It is what those we grieve for did, and what we must do if we want our paths to remain parallel.
