Sharpening our Arrows

I was reading recently in Psalms 127 where it likens children to "arrows in the hand of a warrior." In other words, children are like arrows we shoot into the future because (usually) they outlive us. We tend to use terms like "leaving a legacy" or "impact," but I like the biblical language better. It also helps me when I think about teaching and training the boys. Sometimes, what we say seems to go in one ear and out the other, with almost no impact! Who hasn't been frustrated when having to correct a child "for the umpteenth time"? But I try to keep in mind that reading the Bible to our boys and having them learn scripture, talking to them about the things of God rather than always about temporal things, is like sharpening an arrow that we will one day shoot out into the world. The sharper it is, the further it will go and the more piercing its impact will be.
