While working and preaching, he prayed. And at the end of the day, when He was very tired, he went to bed and rose up very early to pray. Then the servant of Christ asks the Christian about his prayers. No matter how tired Jesus was, but He always and ever prayed. And he also taught these things.
Men always ought to pray, and never to cease.
When the servant of Christ has taught these things, the objection arises. An unlearned Christian will always object against the deeper and heavier parts of Christ's doctrine. So the objection is that we aren't able to pray always and ever. Man cannot pray in the night, but when he does it on the day, that is enough. These are the objections, and though the servant of Christ tries to explain Jesus' example, and says that we have to follow Him, it doesn't help.
