I will make you a wall to this people, a fortified wall of bronze; they will fight against you but will not overcome you, for I am with you to rescue and save you,” declares the Lord. Jeremiah 15:20.
Stability in the fear and faith of God will make a man like a wall of brass, which no one can batter down or break. Only the Lord can make such; but we need such men in the church, and in the world, but specially in the pulpit.
Against uncompromising men of truth this age of shams will fight tooth and nail. Nothing seems to offend Satan and his seed like decision. They attack holy firmness even as the Assyrians besieged fenced cities. The joy is that they cannot prevail against those whom God has made strong in His strength. Carried about with every wind of doctrine, others only need to be blown upon and away they go; but those who love the doctrines of grace, because they possess the grace of the doctrines, stand like rocks in the midst of raging seas.
Charles H Spurgeon
