Luke 16:29-31 . . Abraham said; "They have Moses and the Prophets; let them hear them. If they do not listen to Moses and the Prophets, neither will they be persuaded if someone rises from the dead."

The man, with whom Abraham spoke, called him "father" and he called the man "son". So it's my guess that the man was related to Abraham.

The New Testament hadn't been compiled yet when Jesus told their story so it was appropriate at the time that Abraham direct his son to the Old Testament; which even to this day is a valuable evangelistic tool.

Anyway; my point is: if someone refuses to accept the book of Genesis that the cosmos-- all of its forms of life, matter, and energy --is the product of intelligent design; then it would probably be futile to invite them to church Easter morning to hear a sermon about Jesus Christ's crucified dead body restored to life.
