Jesus’ warnings against unequal yokes are not confined to marriage, but serve as a caution for all Christian relationships. The Unequal Yoke identifies the consequences of linking with worldly desires which detract from our rebirth and regeneration in Christ. Mackintosh aims to correct a discipleship of pessimism and to encourage the Church to become yoked with Christ.
Man’s complete ruin in sin, and God’s perfect remedy in Christ, are fully, clearly, and often strikingly presented [in Mackintosh’s writings].
—Andrew Miller, a leader of the Plymouth Brethren movement
