Proverbs 27:17 Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.
18 Whoso keepeth the fig tree shall eat the fruit thereof: so he that waiteth on his master shall be honoured.
19 As in water face answereth to face, so the heart of man to man.
In these verses we learn first that with metal you cannot us aluminum to sharpen iron you have to iron on iron. Likewise we would not want to be constantly hanging around with trouble makers but with people who share our own moral character if we want to grow. Next we see if we tend the fig tree as we should we will get a good crop from it, the same is true when if we do what we are ask by our boss we will be rewarded.Last we see if we look in clear pool of water we will see our reflection just as if we were looking in a mirror. Then we see if our heart is right we will be able to see when we are in the presence of someone with a like belief in their heart. From these verses we can see we need to be ready to help others grow and in our jobs do the best we can and always try to keep our hearts in tune with God So people can see Him in us.
