Here is a marvelous reminder from J.H. Merle D’Aubigne (Swiss pastor, 1827):
“But, my brethren, if the love of God be in your hearts, and if you feel that, being bought with a price, you ought to glorify God in your bodies and spirits, which are his, where do you love to glorify him rather than in your families and in your houses? You love to unite with your brethren in worshipping him publicly in the church; you love to pour out your souls before him in your closets. Is it only in the presence of that being with whom God has connected you for life and before your children, that you can not think of God? Is it, then, only, that you have no blessings to ascribe? Is it, then, only, that you have no mercies and protection to implore? You can speak of every thing when with them; your conversation is upon a thousand different matters; but your tongue and your heart can not find room for one word about God! You will not look up as a family to him who is the true Father of your family; you will not converse with your wife and your children about that Being who will one day, perhaps, be the only husband of your wife, the only Father of your children!
And listen to this plea to parents…
Parents! if your children do not meet with a spirit of piety in your houses, if, on the contrary, your pride consists in surrounding them with external gifts, introducing them into worldly society, indulging all their whims, letting them follow their own course, you will see them grow vain, proud, idle, disobedient, impudent, and extravagant! They will treat you with contempt; and the more your hearts are wrapped up in them, the less they will think of you. This is seen but too often to be the case; but ask yourselves if you are not responsible for their bad habits and practices; and your conscience will reply that you are; that you are now eating the bread of bitterness which you have prepared for yourself. May you learn thereby how great has been your sin against God in neglecting the means which were in your power for influencing their hearts; and may others take warning from your misfortune, and bring up their children in the Lord! Nothing is more effectual in doing this than an example of domestic piety.
They are not merely to be taught out of some elementary book that they must love God, but you must show them God is loved. If they observe that no worship is paid to that God of whom they hear, the very best instruction will prove useless; but by means of Family Worship, these young plants will grow “like a tree planted by the rivers of water, that bringeth forth his fruit in his season: his leaf also shall not wither.”Thanks to Geoff Kirkland: http://vassaloftheking.blogspot.com/2012/03/importance-of-domestic-piety-holiness.html
