Read Proverbs 21:4  Here in our verse God reminds us of three sins.  We clearly know that the first two are sins, but the last one . . . How can plowing be a sin?  We know that a high look is a sin.  A high look means that someone is snooty.  They think that they are better than everyone else.  Their heart is even proud.  And that is the second sin that our verse mentions.  But the third sin, the plowing of the wicked, how is that a sin?  Well, let's think a minute.  Where did the wicked man get the strength to get up in the morning?  Who makes the wicked man's heart to beat?  Who's air is the wicked man breathing every minute?  Who caused the sun to shine on the wicked man's field?  Who sends the rain to water the wicked man's crops?  But does the wicked man thank the good Lord above for all of His wonderful blessings?  No!  The wicked man says to himself, "I have worked hard and made this crop.  This is mine, and mine alone."  The wicked man doesn't thank God for doing most of the work to make his crop.  The wicked man's ungrateful work is sin before Almighty God.  Everything that we have is God's.  He is so good to us!  We should thank him for all He does for us!  Let's be grateful and not sin before God.
