For not only gross wickedness, but even a carnal mind, and "the friendship of the world," is enmity against God. James 4. 4; Philippians 3. 18, 19. But how do I know that I have the Spirit of Christ?

Answer. I have prayed for him earnestly; this cannot be in vain. Luke 11. 13. He works also hatred and sorrow of sin; rebukes, comforts, and drives me to Christ and to prayer. This is his abiding witness, built upon the word of God, which no man of this world can have, but even the weakest believer enjoys.

Holy, true, and righteous Lord,
I seek to know and do thy will;
Be mindful of thy gracious word,
And stamp me with thy Spirit's seal.

My conscience purge from every blot,
My idols all be cast aside;
Rebuke each vain and sinful thought,
And crucify both self and pride.

Within me thy good Spirit place,
Spirit of health, and love, and power;
And grant me such victorious grace
That inbred sin may reign no more.
