“So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.” (2 Corinthians 4:18 β NIV 2011)
Some of the decisions Christians make seem crazy to people who do not follow Jesus. That is because we are focused on things that others cannot see.
Living for eternity gives you a perspective that is complicated to understand if your focus is somewhere else. And if you do follow Jesus, keep your eyes fixed on the prize no matter what anyone else says.
