Make War with Unbelief

Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. (Philippians 4:6)

John Piper

When I am anxious about getting old, I battle unbelief with the promise, “Even to your old age, I shall be the same, and even to your graying years I shall bear you! I have done it, and I shall carry you; and I shall bear you, and I shall deliver you” (Isaiah 46:4).

When I am anxious about dying, I battle unbelief with the promise that “not one of us lives for himself and not one of us dies for himself; for if we live, we live for the Lord, or if we die, we die for the Lord; therefore whether we live or die, we are the Lord’s. For to this end Christ died and lived again that he might be Lord both of the dead and of the living” (Romans 14:7–9).

When I am anxious that I may make shipwreck of faith and fall away from God, I battle unbelief with the promises, “He who began a good work in you will perfect it until the day of Christ” (Philippians 1:6); and, “He is able to save forever those who draw near to God through him, since he always lives to make intercession for them” (Hebrews 7:25).

Let us make war, not with other people, but with our own unbelief. It is the root of anxiety, which, in turn, is the root of so many other sins. So let us turn on our windshield wipers and use the washer fluid, and keep our eyes fixed on the precious and very great promises of God.

Take up the Bible, ask the Holy Spirit for help, lay the promises up in your heart, and fight the good fight — to live by faith in future grace.
