The importance of taqwa (God-consciousness)

وَمَا ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا لَعِبٌ وَلَهْوٌ ۖ وَلَلدَّارُ ٱلْـَٔاخِرَةُ خَيْرٌ لِّلَّذِينَ يَتَّقُونَ ۗ أَفَلَا تَعْقِلُونَ

And the worldly life is not but amusement and diversion; but the home of the Hereafter is best for those who fear Allāh, so will you not reason?
