How would God have us respond to the doctrine of election? Wayne Grudem helpfully lays out how we should respond to this doctrine,

1. As a Comfort. The New Testament authors often present the doctrine of election as a comfort to believers. When Paul assures the Romans that “in everything God works for good with those who love him, who are called according to his purpose” (Rom. 8:28), he gives God’s work of predestination as a reason why we can be assured of this truth. He explains in the next verse, “For those whom he foreknew he also predestined to be conformed to the image of his Son…And those whom he predestined he also called… justified…glorified” (Rom. 8:29-30). Paul’s point is to say that God has always acted for the good of those whom he called to himself…From eternity to eternity God has acted with the good of his people in mind. But if God as always acted for our good and will in the future act for out good, Paul reasons, then will he not also in our present circumstances work every circumstance together for our good as well? In this way predestination is seen as a comfort for believers in the everyday events of life.

2. As a Reason to Praise God. Paul says, “He destined us in love to be his sons through Jesus Christ, according to the purpose of his will,to the praise of his glorious grace” (Eph. 1:5-6). Similarly, he says, “we who first hoped in Christ have been destined and appointed to live for the praise of his glory” (Eph. 1:12)…the doctrine of election does increase praise given to God for our salvation and seriously diminishes any pride what we might feel if we thought that our salvation was due to something good in us or something for which we should receive credit.

3. As an Encouragement to Evangelism. Paul says, “Therefore I endure everything for the sake of the elect, that they also may obtain salvation in Christ Jesus with its eternal glory” (2 Tim. 2:10). He knows that God has chosen some people to be saved, and sees this as an encouragement to preach the gospel, even if it means enduring great suffering. Election is Paul’s guarantee that there will be some success for his evangelism, for he knows that some of the people he speaks to will be elect, and they will believe the gospel and be saved.
