There is one thing which seldom gets weaker through old age – that is, old Adam; he is as strong in his old age as he is in his young age, just as able to lead us astray when our head is covered with grey hairs, as he was in our youth. We have heard it said that growing in grace will make our corruptions less mighty; but I have seen many of God’s aged saints, and asked them the question, and they have said, “No,” their lusts have been essentially as strong, when they have been many years in their Master’s service, as they were at first, although more subdued by the new principle within. So far from becoming weaker, it is my firm belief that sin increases in power.
