There is only one classroom in which to learn: 1. The work of God. 2. The will of God. 3. The trustworthiness of God. 4. The presence of God. The classroom is where I am now. This is the place appointed by God for my instruction and sanctification - even here: 1. where it seems God is doing nothing (He is, in fact, at work in unseen ways); 2. where His will seems obscure or frightening (He will surely give me peace at last); 3. where He isn't doing what I want Him to (He is doing something better - preparing bread for me when what I asked was in actual fact a stone; or perhaps, He is doing the very thing I prayed for, but in a way incomprehensible to me); 4. where He is most absent (yes, even there His promise holds: I will never leave you or forsake you. My faith must size that written word regardless of the enemy's taunt, "You've been abandoned.").
