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.
By the word of the Lord the heavens were made, and all the host of them by the breath of His mouth. He gathers the waters of the sea together as a heap; He lays up the deep in storehouses. Let all the earth fear the Lord; let all the inhabitants of the world stand in awe of Him. For He spoke, and it was done; He commanded, and it stood fast.” Psalm 33:6-9.
“He [the Lord] loves righteousness and justice; the earth is full of the goodness of the Lord. By the word of the Lord the heavens were made, and all the host of them by the breath of His mouth. He gathers the waters of the sea together as a heap; He lays up the deep in storehouses. Let all the earth fear the Lord; let all the inhabitants of the world stand in awe of Him. For He spoke, and it was done; He commanded, and it stood fast.” Psalm 33:5-9.
