We read in scripture that we are to strive for peace with everyone so that we can see the Lord, and we think that maybe with our own effort we can accomplish this, but along with that it is written that we should also strive for holiness, and we have no idea how we can possibly become holy. Perhaps this is because we see who we are, and the decrepit nature of our starting point. When we compare this with the ultimate goal of achieving holiness, we wonder how it is possible to do that. So how do we become holy? Is holiness something that man can accomplish, or is it unobtainable for us?
