In the sermon 'What Would We Do if the Foundations were Destroyed,' Conrad Mbewe explains that the foundations were destroyed in Genesis 3 due to sin, which devastated human nature. The solution to this destruction is found in Jesus Christ, who is the fulfillment of God's promise of the Messiah. The sermon emphasizes the importance of spreading the gospel in homes, churches, and the world as a means of transforming lives from within. Christians are encouraged to actively engage in building God's kingdom by acting as salt and light in the world, rather than retreating in the face of challenges. Although a golden age may not be achieved, the focus remains on fulfilling Christ's mission by righting wrongs and challenging sinful lifestyles, ultimately bringing people to Christ.

The Bible's answer, first of all, is that the foundations were destroyed in Genesis 3. That's where sin devastated human nature. And to say what does the righteous do, the answer is in the person of our Lord Jesus Christ. The prototype being the seed of the woman that is spoken about by God as the promise of the first promise of the Messiah. And therefore we need to realize that what the righteous need to do is to see the redemption that God has not only promised but fulfilled in the person of our Lord Jesus Christ and to ensure that that gospel goes forth.

It goes forth in our homes, it goes forth in the church, It goes forth in the world. It's God's instrument by which men and women are not only brought to repentance and faith in Christ, but men and women are transformed from the inside out. And having thus been transformed, they get out there in order to transform God's world as salt and light. So We don't rush to go and hide because the foundations have been destroyed. In fact, we ensure that we get out there with the gospel in order to ensure that wrong is righted, that which is a life of sin is challenged afresh, where individuals are brought to Christ.

And yeah, we may not see the golden age, but the point is we will be doing what Christ has wanted us to do to get busy with the building of his kingdom.
