The lesson drawn from Proverbs 15:3 shows us that: 1. the Lord sees all things; the bad things done and He is not happy; the good deeds, and he’s only happy with the good deeds done by Christians (Isaiah 64.6). 2. The Lord knows all things (Psalm 139:1-4). He knows our thoughts, our words and our deeds; and the wicked will not go unpunished. The lesson ends by showing that, without His friendship with us, we can never please him. Therefore, we need to call on him to be our friend.
