The varied classes in the school of God last a lifetime. Each believer receives individualized instruction—public and private. There are exams in the school of God (1 Peter 1:7). They are rarely meant to eliminate, but may necessitate repeating the class. But all will graduate at the same time (Phil. 1:6), appearing completely formed to the perfect likeness of Christ (2 Tim. 3:16; Titus 2:12; Job 36:22; 1 John 3:2; Phil. 3:21)!
