David Wilkerson emphasizes that the Holy Spirit dispels fear and instills joy in believers, allowing them to rejoice in God's assurance of victory. Many Christians, however, live in a state of mourning, perceiving God as a harsh taskmaster rather than a loving Father. The core issue is not sin, but a lack of trust in God's grace and kindness, as Jesus has already dealt with sin at Calvary. Wilkerson encourages believers to focus on God's desire to bless and reward them, rather than their failures. Ultimately, God longs for us to understand His loving nature and the forgiveness available through Christ.
