His Strength, Our Stregnth
The salvation of the righteous is of the LORD: he is their strength in the time of trouble.
Psalm 37:39
Whatever the circumstances, whatever the call, whatever the duty, whatever the price, whatever the sacrifice—His strength will be your strength in your hour of need.
There are physical benefits that come from Christian living. Sin and the sense of inner unworthiness impair physical and mental well-being. The sense of physical impurity and physical immorality, the sense of hatred directed toward our fellow men, the awareness of our own inadequacy and frustration and our inability to achieve the goals to which we aspire—these are often the real reasons for physical and mental illness. The sense of guilt and sin that the natural man carries within himself renders him unfit for the performance of his duties, and renders him sick in both mind and body. It was no accident that Jesus combined healing with His preaching and teaching when He was on earth. There is a very special relationship between the life of the spirit and the health of the body and mind.
Peace with God and the peace of God in our hearts and the joy of fellowship with Christ have in themselves a beneficial effect upon the body and mind and will lead to the development and preservation of physical and mental power. Thus, Christ promotes the best interest of the body and mind, as well as of the spirit.
Our Father and our God, I have such happiness and joy in being Your child. I feel Your strength in my soul and in my body. Your Spirit within refreshes me day by day, and I celebrate my union with You. I rest in Your quiet peace, and I rejoice in hope of eternity with You. Because of Christ Jesus. Amen.
