By faith Noah…prepared an ark to the saving of his house… -Hebrews 11:7

He was saved and his house. Oh, that God would give to every preacher of righteousness this full reward-himself and his house! O my brothers in the ministry, there is no greater joy for us than to know that our children walk in the truth! Perhaps some of you fear the Lord; and yet He has never given you your Shem, Ham, and Japheth. Alas! it may even happen that she that lieth in your bosom does not yet know the Lord. Nevertheless, be you faithful to your God, and to the souls of men. Hold the truth, if you stand alone. Even if in your own house you find your worst foes, hold on, and never doubt. Do not come down a step or two as to holiness, nor seek a lower platform upon which to meet more cordially an ungodly world. Believe in the Lord Jesus Christ and in the power of the ever-blessed gospel. That is the one business of your life; and I believe that if you have faith in the Lord as to your family, your beloved ones shall be given you as a prey. Remember the Philippian jailer, to whom Paul said, “Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.” Do not rest content with half the promise. Grasp firmly the words, “and thy house.” Have you an Ishmael? then get alone, and, like Abraham, cry to God, “O that Ishmael might live before thee!” God will hear your prayer and bless Ishmael also. Oh, what a privilege it will be if you yourself and all your house are saved! ~ C.H. Spurgeon
