How can God open the ears of the spiritually deaf?

The act of opening the ears of the spiritually deaf is a sovereign work of God, accomplished by the Holy Spirit applying the gospel to the hearts of individuals. As seen in the account of the deaf man in Mark 7, where Jesus commanded, 'Ephphatha, be opened,' we understand that it is God who must initiate this work. The apostle Paul also affirms this in 1 Corinthians 2:10, stating that 'God hath revealed them unto us by his Spirit.' Therefore, when the gospel is preached, it is the Spirit of God that takes those words and uses them to awaken faith in the hearts of the hearers. This miraculous opening of the ears and hearts is rooted in God’s electing grace.
