1. The troubles of the church have given some occasion to question God's care and concern for it, v. 14. Zion, in distress, said, The Lord has forsaken me, and looks after me no more; my Lord has forgotten me, and will look after me no more. See how deplorable the case of God's people may be sometimes, such that they may seem to be forsaken and forgotten of their God; and at such a time their temptations may be alarmingly violent. Infidels, in their presumption, say God has forsaken the earth (Ezek. viii. 12), and has forgotten their sins, Ps. x. 11. Weak believers, in their despondency, are ready to say, "God has forsaken his church and forgotten the sorrows of his people." But we have no more reason to question his promise and grace than we have to question his providence and justice. He is as sure a rewarder as he is a revenger. Away therefore with these distrusts and jealousies, which are the bane of friendship.
