God will sovereignly use persons, things, and events to empty us of everything that has filled us and to take away every preoccupation so that we may have an increased capacity to be filled with God—Luke 1:53; Matthew 5:6. (2014 Summer Training, msg. 6 outline)
Time is needed for life to mature. …Maturity is a matter of the enlargement of capacity. You must allow God to give you time to suffer beyond measure; then your capacity will be enlarged.
To escape God’s arrangement just one time is to lose an opportunity to have our capacity enlarged. This will prolong the time required for life to mature in us and will even require us to make up this lesson in order to reach maturity. A believer can never be the same after passing through suffering. Either he will have his capacity enlarged or he will become more hardened. For this reason, when believers are passing through suffering, they must pay attention and they must realize that maturity in life is the sum total of receiving the discipline of the Holy Spirit. People may see a person who has matured in life, but they cannot see the accumulated discipline of the Holy Spirit which that person has received secretly day by day throughout the years. (Watchman Nee—a Seer of the Divine Revelation in the Present Age, ch. 19)
