The work of the Spirit is very largely a hidden, secret work, deep, something which the flesh cannot take hold of and sport itself in.... He must come down to the essence of a peculiar people, and so very often keeps away the spectacular, the demonstrative, and the Holy Spirit does His work secretly, hiddenly, but mightily; no advertisement, no noise, but something is going on, deep, strong, mighty; God is doing things. The world looks on and sees nothing that it can write up. And even half-consecrated Christians are dubious about the whole thing. They do not see what the remnant of the flesh in them craves to see of the outward evidences of a movement of God, but God is doing it.
