“You shall not worship them or serve them; for I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children, and on the third and the fourth generations of those who hate Me.” Deuteronomy 5:9
This seemingly unwarranted penalty imposed on the innocent grandchildren of the idolater cannot possibly negate the later promise of God through the prophet Ezekiel: “The person who sins will die. The son will not bear the punishment for the father’s iniquity, nor will the father bear the punishment for the son’s iniquity; the righteousness of the righteous will be upon himself, and the wickedness of the wicked will be upon himself” (Ezekiel 18:20).
And certainly it cannot obviate the clear promise of Christ Himself in the last chapter of the Bible: “let the one who is thirsty come; let the one who wishes take the water of life without cost” (Rev. 22:17). Anyone who desires to do so may accept the Lord’s gracious offer of salvation, regardless of the possible wickedness or anti-Christian religion of any of his ancestors.
At the same time, a man should realize that his decision to follow a false religion and then bring up his children in that false religion will almost certainly affect his grandchildren and great grandchildren, as well. Many of the latter will actually be children while their great grandfather is still alive. It is a simple fact that most children (though not all) will continue in their parents “religion.” They can, if they wish, choose to leave their parents’ religion and become Christians, but most will not.
What a great responsibility, therefore, each father has! And what a great responsibility the church has to take the gospel to the ends of the earth (Acts 1:8). How beautiful are the feet of those who bring glad tidings of good things (Rom 10:15).
