How many believers on the Lord Jesus are held in bitter bondage of soul, sometimes for long years, by the fear that it is presumption on their part to take the ground of being sure of salvation. But to believe God is surely no presumption. On the other hand to refuse to believe God's testimony is indeed presumption. How honoring to take God at His word. Here is one passage of Scripture out of many, that makes it abundantly plain that we can know for certain, that believing on the Lord Jesus we are saved, and that the very moment we believe. We read, "Verily, verily, I say unto you, He that heareth My word, and believeth on Him that sent Me, HATH everlasting life, and SHALL NOT COME INTO CONDEMNATION; but IS passed from death unto life." (John 5:24).
This verse is sufficient to banish all fear, and to make it evident that it is not presumption on our part to say that we are saved. Rather it is God-honoring to take God at His word, and true humility to accept the assurance He offers.
