Prayer is talking with God about what we’re thinking and doing together; it is co-laboring with God to accomplish the good purposes of his kingdom. Prayer almost always involves other disciplines and spiritual activities (e.g., study, meditation, worship, solitude, or fasting).
Don’t seek to develop a prayer life — seek a praying life. A “prayer life” is a segmented time for prayer. You’ll end feeling guilty that you don’t spend more time in prayer. Eventually you’ll probably feel defeated and give up. A “praying life” is a life that is saturated with prayerfulness — you seek to do all that you do with the Lord.
