God is faithful, and he will not let you be tested beyond your strength, but with the testing he will also provide the way out so that you may be able to endure it. (1Cor 10:13)
Jesus told his disciples a parable, “Can a blind person guide a blind person? Will not both fall into a pit? No disciple is superior to the teacher; but when fully trained, every disciple will be like his teacher.” Luke 6:39–40
