a : of or relating to time as opposed to eternity

The word "temporal" means simply something that is temporary. Here today and gone tomorrow. It is something that has no lasting value. This world is temporal, our material possessions are temporal. In fact most things in our life are temporal. Yet, we put great value on them for a while.
Look not to the things that are seen but to the things that are unseen; for the things that are visible are temporal, but the things that are invisible are everlasting.
~2 Corinthians 4:18
