Proverbs 12:15 says, The way of a fool is right in his own eyes: but he that hearkeneth unto counsel is wise.  Some people believe that they know more than everyone else, so in their own eyes they are always right.  Those who are truly wise are willing to listen to others, especially those who offer Godly guidance.  Verse sixteen states, A fool’s wrath is presently known: but a prudent man covereth shame.   Matthew Henry says that this means that the wicked give in to their desires, no matter what.  When they are angry, they lash out.  The prudent, or God fearing person, may feel angry, but they do not allow that anger to rule them.  Verse seventeen declares, He that speaketh truth sheweth forth righteousness: but a false witness deceit.  Verse eighteen says, There is that speaketh like the piercings of a sword: but the tongue of the wise is health.  Some people say things that hurt others badly, but if we are God's people, we will say things that help and encourage others.  Verse nineteen adds,  The lip of truth shall be established for ever: but a lying tongue is but for a moment.  When we speak the truth of God, it is everlasting.  Lies, on the other hand, are but for the moment.  Anything that is taught that is in opposition to God's word will never last.  Verse twenty says, Deceit is in the heart of them that imagine evil: but to the counsellers of peace is joy.  Those who imagine evil have it come from their heart, or innermost being .Those who follow the teachings of Christ will be lead to joy.  Verse twenty-one states, There shall no evil happen to the just: but the wicked shall be filled with mischief.  This does not mean that nothing bad will ever happen to the just, or those who are God's people, but that spiritually we are always safe and secure with God.  The wicked will always be looking for ways to cause trouble for God's people.  Verse twenty-two states, Lying lips are abomination to the LORD: but they that deal truly are his delight.  God hates lying, so as followers of Christ, we should always speak the truth, even if it costs us materially to do so.  What we say is important to God, and should be consistent with the way we live.  Verse twenty-three proclaims, A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness.  We are not to brag about our wisdom, but are simply to be guided by it and glorify God by it.  The foolish, the lost of the world, can never share true wisdom, since this comes from God, but can only speak foolishness.  Verse twenty-four states, The hand of the diligent shall bear rule: but the slothful shall be under tribute.  God does not expect us to sit idly by awaiting the return of Christ, but to be diligent in doing what He has called us to do.  Verse twenty-five says, Heaviness in the heart of man maketh it stoop: but a good word maketh it glad.  I believe this is saying that sorrow can cause a person to suffer physically, but a word of encouragement or empathy can help a person overcome that sadness.  We should always attempt to encourage and uplift those who are suffering in sorrow.  Verse twenty-six says, The righteous is more excellent than his neighbour: but the way of the wicked seduceth them.  This does not mean that we are to act superior to our neighbors.  We are to live under the leadership of God and to share His gospel.  Even as we do, the wicked, those who do not follow God, will tempt people to follow the way of the world.  Verse twenty-seven says, The slothful man roasteth not that which he took in hunting: but the substance of a diligent man is precious.  This is simply stating that the lazy, or slothful, people do not make the effort to provide for their needs and often have to rely on others.  The diligent are more likely to have food to feast on.  This does not mean that everyone who is hungry or in need is lazy, but that those who are lazy are more likely to be hungry or in need.  Verse twenty-eight proclaims, In the way of righteousness is life; and in the pathway thereof there is no death.  This refers to a person's spiritual life.  Once we accept Christ as our Savior and Lord, we are on the path of everlasting life with God, and nothing can knock us off that path.
