“Then the Lord saw that the wickedness of man was great in the earth, and that every intent of the thoughts of his heart was only evil continually.” Genesis 6:5.
“I will leave in your midst a meek and humble people, and they shall trust in the name of the Lord. The remnant of Israel shall do no unrighteousness and speak no lies, nor shall a deceitful tongue be found in their mouth; for they shall feed their flocks and lie down, and no one shall make them afraid.” Zephaniah 3:12-13.
How do we know what is good? The Bible tells us that God is good. In fact, it speaks of His goodness throughout Scripture.
“The Lord is good to those who wait for Him, to the soul who seeks Him. It is good that one should hope and wait quietly for the salvation of the Lord.” Lamentations 3:25-26.
