Pro 27:17 Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.
Have you ever sharpened a knife? You have to have the right angle and pressure. Too much you do more harm than good, not enough it does nothing at all. Its the same with a friend we are to lift them up and encourage them to use the gifts God blessed them with. We need to know the angle to reach them and how much pressure to apply (that’s where the spirit comes in) and you might even have to put a little water on them. Living water that is.
