Genesis 7:1

1. Come thou and all thy house into the ark “The long period of warning and preparation had now nearly passed . The one hundred and twenty years had rolled on, and were now within a week of their termination . The ark itself was at length completed and ready for occupancy . Against all the reviling of men and the temptations of Satan, Noah’s faith had triumphed . Now it remained to introduce to the majestic structure its tenants, and God’s time has come for them to enter . The command to enter is a gracious command . The plan of God from the beginning has been to dispense his grace by a household covenant . He has been pleased to propagate his Church by means of a pious posterity .

Hence we have the household baptisms in the Christian Church.” Jacobus.
