Ecclesiastes 5

1 We are to come to God with reverence and with listening and obedient hearts. Fools come to places of worship to make a show of their self-righteousness and sacrifices, while inside they are unrepentant sinners.
2 In 1 Th 5:17 we are told to "pray without ceasing." This does not mean that we should pray without thinking. God already knows our needs, so we do not need to babble endlessly to Him (Mat 6:7-8). We must remember that prayer is a conversation. During prayer, we should also be listening carefully for God's direction.
3 According to Wycliffe, the first part of this proverb refers to the phenomenon of dreaming about working after a busy day. A foolish person will babble on and on before God without sincerity, thought, or desire to listen.
4 God has ultimate authority and power and does not need anything from us. Yet, some people feel that they must promise to do things for God in exchange for favors (usually selfish ones). When we make a promise to God, we become obligated to fulfill it. If we do not, we are guilty of sin.
8 Abuse of power is common in a hierarchical society. People are used to being obedient to those over them. The officials at the top are often ruled by greed. The result is that the poor are ignored, abused, or manipulated. They have no power, and selfish rulers feel the poor have little value.
9 This is the mantra of most businesses today. The only important thing seems to be earning a profit (i.e., "the bottom line"). It seems that at the first sign of sliding profits a company will fire employees. The idea is that if they can keep the incoming money at the same level and pay for fewer employees, then their profit margin goes up. In the process, former employees are left without jobs while those that remain have to make up for the loss of available labor. The sad thing is that many of these companies could retain their employees until markets turn around. However, passion for money often overrules compassion for people.
10 Money and possessions can never satisfy us, because they do not address some of our most important needs. For example, we need loving relationships. Wealth can not love, and indeed often interferes with our relationships with people and God.

When a man dies, he leaves his wealth behind and stands before God without material trappings. If he does not possess any "spiritual" wealth, then he has nothing to offer God. Money can not purchase salvation.
