Paul's Joy in Christ: Studies in Philippians by A T Robertson and published by Classics.
Many modern critics fail to understand Paul because they fail to understand Jesus, and therefore do not know Jesus as Paul knew him—a critical error. In Paul’s Joy in Christ: Studies in the Philippians, Robertson asserts that “nowhere is the tender side of Paul’s nature better shown than here: his delicacy, his courtesy, his elevation of feeling, his independence, his mysticism, and his spiritual passion.” This volume is derived from a series of lectures delivered at the Northfield Conference for Christian workers in August, 1913.
