Spiritual conditions are inseparably connected with our physical life. The flow of the divine life-currents may be interrupted by a little clot of blood; the vital current may leak out through a very trifling wound.
If you want to keep the health of Christ, keep from all spiritual sores, from all heart wounds and irritations. One hour of fretting will wear out more vitality than a week of work; and one minute of malignity, or rankling jealousy or envy will hurt more than a drink of poison. Sweetness of spirit and joyousness of heart are essential to full health. Quietness of spirit, gentleness, tranquility, and the peace of God that passes all understanding, are worth all the sleeping draughts in the country.
We do not wonder that some people have poor health when we hear them talk for half an hour. They have enough dislikes, prejudices, doubts, and fears to exhaust the strongest constitution.
Beloved, if you would keep God's life and strength, keep out the things that kill it; keep it for Him, and for His work, and you will find enough and to spare.
