Rather than being an excuse for neglecting evangelism, the truth of Divine Sovereignty is a motivation to diligence in evangelism. While Paul was in Corinth and was discouraged because of opposition that he was receiving from the Jews, the Lord Himself appeared to Paul in a vision and said, “Do not be afraid, but speak, and do not keep silent; for I am with you, and no one will attack you to hurt you; for I have many people in this city” (Acts 18:9-10).
How, then, do you pray? Do you ask God for your daily bread? Do you thank God for your conversion? Do you pray for the conversion of others? If the answer is ‘no’, I can only say that I do not think you are yet born again. But if the answer is ‘yes’—well, that proves that, whatever side you may have taken in debates on this question in the past, in your heart you believe in the sovereignty of God no less firmly than anyone else. On our feet we may have arguments about it, but on our knees we are all agreed (Packer. Evangelism and the Sovereignty of God. p. 17).
