From a CJ Mahaney interview (emphasis mine):
…I view reading and study as one of the most important ways I can serve the church. So it is not a selfish act for me to set aside this time. It is really the most effective way I can serve this church, by tending to my soul and by preparing for the various forms and expressions of ministry. The best way I can serve a church is by responding to the command to watch your life and watch your doctrine (1 Tim 4:16). It is the example of a pastor over a period of years and decades that will make a difference in the life of a congregation. And therefore I want to guard my heart from growing familiar with the pastoral world, growing familiar with God’s Word, growing familiar with corporate worship, growing familiar when I am listening to preaching, growing familiar when I am taking communion, growing familiar with God. I want to guard my heart from that. And the best way I can do that is by attending to his Word and applying his Word to my heart on a daily basis. I think that is the most effective way I can serve those I care for and those I have been called to serve and lead.
