What does it mean that Christ has to touch our hearts for salvation?

In the sermon, it is emphasized that just as Jesus touched the ears of the deaf man to heal him, He must also touch our hearts to make us spiritually alive. Without this divine touch, we will remain spiritually deaf and incapable of receiving the truth of the gospel. This touch signifies a transformative work of the Holy Spirit where He imparts new life and faith within us. We see in 2 Corinthians 5:17 that anyone in Christ is a new creation, indicating that salvation involves a radical change initiated by Christ Himself. Thus, His intervention is necessary for us to understand and accept the gospel.
