When Not to Pray, but to Act
By Dr Martyn Lloyd-Jones
EPHESIANS 4:22-24 Put off the old man : a definite command; the need to think and to apply doctrine; sanctification is not by faith only; the first essential for the believer is to remind himself who he is; a prayer of belief and not unbelief; the importance of a consistent life; obedience to the Gospel; do not feed the old man, but mortify the flesh.
