God does not want us to be always up or to be always down. Even in nature the alternating of day and night testifies of this. There is no such thing as an unending day or night. Rather, there is the alternating of day and night, night and day. God did not create us so that we would have a day or night that would last for many years. This may be according to our way, but it is not according to God’s way.

Young people, you must know your rule, your limit. This means that you must know how much God has measured to you, how much He has apportioned to you. This restriction, this limitation, is a very practical dealing with our flesh. Our natural man wants to be without limitation. However, God knows our problem. Therefore, He sets up boundaries and restrictions so that we may stay within the measure that He has apportioned to us.
