V.13-20 Here is the happy side. There is no happy life like the life of a person who walks with the Lord. Because He only can give joy. Solomon could tell us what God had promised him, if he put the Lord first (1 Kings 3:11-13). Everything Solomon had, came from God.
V.21-26 A believer easily becomes upset if he is not fully trusting the Lord. These verses give us assurance that when the believer does live with a good conscience toward God, a quiet confidence in the Lord comes over him. When something happens suddenly; he is steady.
V.27-30 Our hearts are deceitful as well as suspicious, so we need to be simple and honest in our dealings with others.
V.31 Don’t envy those who do wicked things and seem to get away with them.
V.33-35 It is a very great wickedness to be mocking others who want to please the Lord.
V.35 The wise will understand, and they will inherit glory!
