What is more Important: Bible Study or Prayer?

According to Donald Whitney in Spiritual Disciplines for the Christian Life, “No Spiritual Discipline is more important than the intake of God’s Word.”

Put in context of his writing, Whitney asserts that reading the Bible is the most important spiritual discipline for Christians.  I have some other ideas–namely, that prayer is the most important discipline.  Its important to read about God in the Bible and to learn from God’s Word, but is that more important than talking to God directly?

What do you think?
