While that may sound like an easy choice, the reality is that most people choose to build on sand the temporary foundations of this life. Think about it people build houses on earthquake faults, on cliffs overlooking the ocean, on sandy beaches. Because of the view, because it s beautiful. And even when they know that earthquakes have hit there before, or other houses have slid down the cliff during heavy rains, or that the storms have sucked the sand right out from under homes along the shore, they choose to build their houses on foundations that are not rock. Some even will rebuild a house after one has been destroyed.
People also build their lives on temporary foundations.
They put their career ahead of family and friends. They allow the busyness and activities to control their lives. They also trust in their money, or possessions. As long as their stock portfolio is increasing they assume they are safe. Some think that fame, or power, or status will be substantial enough to protect them for life.
