A.W. Tozer wrote in his book The Root of the Righteous:
We can prove our faith by our committal to it, and in no other way. Any faith that does not command the one who holds it is not a real belief; it is a pseudo belief only. And it might shock some of us profoundly if we were brought suddenly face to face with our beliefs and forced to test them in the fires of practical living. Many of us Christians have become extremely skillful in arranging our lives so as to admit the truth of Christianity without being embarrassed by its implications. So wide is the gulf that separates theory from practice in the church that an inquiring stranger who chances upon both would scarcely dream that there was any relation between them. An intelligent observer of our human scene who heard the Sunday morning sermon, and later watched the Sunday afternoon conduct of those who had heard it, would conclude that he had been examining two distinct and contrary religions.
Christians habitually weep and pray over beautiful truth, only to draw back from that same truth when it comes to the difficult job of putting it in practice.
When we hear the New Testament with willing, open hearts, the Gospel will penetrate our very lives and break them open, energizing our eyes, our ears, our hands, our legs—every part of us. And when we allow the Gospel to energize us, we become vessels in the Lord’s hands, pouring out our prayers, finances, reputation, lifestyle—and ultimately our very lives.
Do we have to be “somebody” to hear the call of God and make a difference? In my own life I have seen time and again how God uses “nobodies.” Sometimes I feel insecure. At other times I feel overwhelmed with all that I know needs to be done. Again and again I struggle and fail.
Where do I go when this happens? To the cross! How many times? Many times a day, if needed. The cross is the place where I can go and say, “Lord, I am Yours, along with all my weaknesses. But Your grace alone is what I need to serve You.”
Perhaps you feel you are useless to the Lord, that you are not good enough, or that you have already wasted your life. But you are still in His hand. Don’t you know that every day with Jesus is a new beginning? The Lord never condemns you or says, “Sorry, you didn’t make it.” His mercies, He tells us, are new every morning (see Lamentations 3:22–23). Whether you have lost 7 days or 70 years, the Lord says to you, “Return to me with all your heart. . . . I will repay you for the years the locusts have eaten” (Joel 2:12, 25).
The Lord does not ask you to be a success or a superstar. In fact, if you truly desire to be a world-changer give your weaknesses to God so He can use you. All He requires is a weak, brokenhearted child who will surrender at the foot of the cross.
