Your prayer for your sister is a tender and right thing, and it is good that you bring her journey before the throne of grace before she sets her foot upon the road. If we walk aright, we shall never venture upon a single day without first seeking Divine protection, and how much more when a long journey lies before one we love.
Be comforted by what the Scripture declares, that He shall cover thee with His feathers, and under His wings shalt thou trust. It was something more than the protection which a soldier would give to a comrade, it was the protection of a mother for her young. There is love in it, there is heart working in it all, and not only protection from danger is vouchsafed, but a sense of comfort and happiness is communicated, making the child of God feel that he is at home under the shadow of the Almighty. The same promise tells us that He shall give His angels charge over thee, to keep thee in all thy ways. This protection is perpetual as well as personal.
He who travels on the King's Highway is under the King's protection. You will always need Divine and angelic keeping, for God would not have charged His angels to keep His people in all their ways if they did not need protection in all their ways. How safe we are, then, when embarked in the good ship of Providence, with such a Captain who has forearranged and foreordained all things from the beginning even unto the end. Much of the pleasantness of a journey lies in unexpected views which burst upon the traveler, but our comfort is that each hour is safe, for God has made it so, and each place of difficulty and of danger shall still be secure to those that rest beneath the wings of the eternal God.
So do not be nervous when the storm gathers or the road seems long. Put implicit confidence in His guidance, for the man that rests in God finds God's protection wonderfully spread over him.
Let us pray together for her. Heavenly Father, we thank Thee for Thy loving care which never slumbers. We ask Thee in the name of Jesus Christ, Thy Son, to set Thy gracious hand upon this dear sister as she travels. Surround her with Thy presence, give charge to Thy angels to keep her in all her ways, preserve her from the dangers of the road and bring her safely to her journey's end according to Thy good will. Let her know that she abides under Thy shadow and is safe, safe and near to Thee. Grant her peace, and grant to those who love her a quiet confidence in Thy faithful keeping. We ask this in the precious name of Jesus, our only hope and shelter, Amen.
