II 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.

Hath God forgotten to be gracious? hath he in anger shut up his tender mercies?—I said in my haste, I am cut off from before thine eyes: nevertheless thou heardest the voice of my supplications when I cried unto thee.

Shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? I tell you that he will avenge them speedily.—Wait on the Lord, and he shall save thee.—Rest in the Lord, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.

There are times when doing nothing is better than doing something. Those are the times when only God can do what is needed. True faith trusts Him then, and Him alone, to do the miracle. Moses and Jehoshaphat knew this secret; they knew the same Lord and the same Divine grace.

As the pursuing Egyptians trapped the helpless Israelites at the Red Sea, Moses said: “Do not be afraid. Stand firm and you will see the deliverance the LORD will bring you. . . . The LORD will fight for you; you need only to be still” (Exodus 14:13–14).
