“Though our outer man is decaying, yet our inner man is being renewed day by day.” (2 Corinthians 4:16)
The Christian life is a matter of daily practice (1 Tim. 4:15). It is important, however, to have a proper understanding of the focus and content of this practice. The focus of our practice should not be on outward things such as ethical behavior, but rather on being inwardly renewed by the operation of the divine life. Similarly, the content of our practice should not be based on outward rules and procedures, but rather on the exercise of the spirit, especially in our reading and speaking of the Word of God, which releases the operation of the divine life.
All of the books by Watchman Nee and Witness Lee in this category speak of the importance of daily life practices and assist in bringing the believers into a daily renewing in life.
