These coins have some monetary value, but today we are going to use the coins to illustrate the passage of time.
An average person, in moderately good health, can normally live to be at least 75 years old. Many people can live quite a bit longer than this, but we will use 75 years as an average life span.

For each year we live, we will take one coin out of the bag. There are a limited number of coins in this bag, just as we will have a limited amount of time here on earth. None of us know exactly how long we will remain in our earthly bodies. During our time here on Earth we can choose to use the time we have to follow God and lead lives that are pleasing to God or we can choose to lead lives that sadden God.

Our earthly life will last a short time, whereas our spiritual life will last for eternity. Eternity is forever and without end. We could fill this room from top to bottom with bags containing 75 coins and this would not represent even a dot on the timeline of eternity. We could fill this entire building with bags containing 75 coins and this would still not represent even a dot on the timeline of eternity.

(Read 1 Peter 1:23-25.) Yes, our earthly lives are like blades of grass here today and gone tomorrow.

We can be wise and use the years that we have here on earth to live a life that is pleasing to God and store for ourselves treasure in Heaven that will last forever. (Read Matthew 6:19-20) Or, lead our lives selfishly and reject God; only to spend eternity separated from Him. (Read Matthew 7:22-23)
