Proverbs 17:18 A man void of understanding striketh hands, and becometh surety in the presence of his friend.
19 He loveth transgression that loveth strife: and he that exalteth his gate seeketh destruction.
20 He that hath a froward heart findeth no good: and he that hath a perverse tongue falleth into mischief.
21 He that begetteth a fool doeth it to his sorrow: and the father of a fool hath no joy.
Her in these verses we see several things that cause sorrow in peoples lives. First if you sign on note with someone you might as well be saying you are going to pay for the item bought. It is not wise to sign on note with someone it only cause bad feelings. Next we someone who likes to cause strife in other peoples lives and these people like to hide behind high walls which open them up to destruction by thieves and robbers. Then there are those that just have a sinful heart which leads to speaking with a perverse tongue. Not only saying words that are not nice but telling lies to hurt other people. Last we have a situation that hits home with many families where a child goes off and gets into some terrible trouble. We do our best to raise our children right but when then mess up it hurts us and sometimes people look down on the parents for the faults of the children. In all these situations we as a christian need to try to reach these people get them see the error of their ways and turn their life over to Christ.
