There is nothing selfish about exercising special care for your own family and earnestly seeking their salvation. In God’s providence, your family is the first, primary sphere of your responsibility. It is not wrong, but most natural and proper, that your desire for the salvation of others should, first of all, be towards your own family.
God has not reversed the laws of nature. He has sanctified them by the rule of his grace. It is only right that Abraham should pray for Ishmael, that Hannah should pray for Samuel and that David should pray for Solomon. It is only right that Andrew should first find his brother Simon and bring him to the Saviour, and that Eunice should teach her son Timothy the way of salvation and life in Christ.
Let us resolve, by the grace of God, to do whatever can be done to bring every member of our family into the kingdom of Heaven.
