Has the God who prepared the gospel for all people groups also prepared all people groups for the gospel?

Don Richardson has studied cultures throughout the world and found startling evidence of belief in the one true God within hundreds of them. In Eternity in Their Hearts, Richardson gives fascinating, real-life examples of ways people groups have exhibited terms and concepts in their histories that have prepared them for the gospel.

Eternity in Their Hearts shows how God uses redemptive analogies to bring all men to Himself, bearing out the truth from Ecclesiastes that God "has also set eternity in the hearts of men".(3:11)
