The writer once met, in a South Wales town, a man who seemed in deep exercise about his soul's salvation. One question was perplexing him greatly, “Is my faith in Christ genuine?” But the test he had been making use of to settle the difficulty was this, "Can I really find in myself the proper marks of a Christian?"
The search, however, had evidently been very disappointing. As he had a small business of his own, a simple question in connection with it was put to him: “When a new customer comes to your shop and wants credit, whose character do you investigate, your own or his ?” “Oh, his, of course,” he promptly replied. Yes. The genuineness of your confidence in the customer could not be determined by any worthy features in yourself. In like manner, therefore, if you want to ascertain the genuineness of your faith in Christ, all you need is to make sure of the genuineness of His title to be trusted. Let any reader in like difficulty consider this. “They looked unto Him and were lightened, and their faces were not ashamed” (Psa. 34:5).
The discovery of His personal trustworthiness disperses every doubt. But should the eye be taken off Him after that, and a doubt intrude; just ask yourself, "Do I now consider Him unworthy of my confidence?" Let your lips repeat His saving name, the Name of Jesus; look up into His face, and every doubt will vanish.
