Hebrews 3:9-12

There your fathers tested me and tried my patience even though they saw my miracles for forty years they still doubted me! This ignited my anger with that generation and I said about them, ‘They wander in their hearts just like they do with their feet, and they refuse to learn my ways.’ My heart grieved over them so I decreed: ‘They will not enter into my rest!’ ” So search your hearts every day, my brothers and sisters, and make sure that none of you has evil or unbelief hiding within you. For it will lead you astray, and make you unresponsive to the living God.
