The Lord will be with you. (2 Chronicles 20:17)
This was a great mercy for Jehoshaphat, for a great multitude had come out against him; and it will be a great mercy for me, for I have great need, and I have no might or wisdom. If the Lord be with me, it matters little who may desert me. If the Lord be with me, I shall conquer in the battle of life, and the greater my trials the more glorious will be my victory. How can I be sure that the Lord is with me?
For certain He is with me if I am with Him. If I trust in His faithfulness, believe His words, and obey His commands, He is assuredly with me. If I am on Satan’s side, God is against me and cannot be otherwise; but if I live to honor God, I may be sure that He will honor me.
I am quite sure that God is with me if Jesus is my sole and only Savior. If I have placed my soul in the hands of God’s only-begotten Son, then I may be sure that the Father will put forth all His power to preserve me, that His Son may not be dishonored.
Oh, for faith to take hold upon the short but sweet text for today! O Lord, fulfill this word to Thy servant! Be with me in the house, in the street, in the field, in the shop, in company, and alone. Be Thou also with all Thy people.
