What God requires of us he himself works in us, or it is not done. He that commands faith, holiness, and love, creates them by the power of his grace going along with his word, that he may have all the praise.
Matthew HenryIt is our duty not to not only hold fast, but to hold forth the Word of life; not only to hold fast for our own benefit, but to hold it forth for the benefit of others, to hold it forth as the candlestick holds forth the candle, which makes it appear to advantage all around, or as the luminaries of the heavens, which shed their influences far and wide.
Matthew Henry
