Mankind has gone astray. Sin has separated us from a holy God, but now comes the good news. What man could not do to save himself, God accomplished on the cross. Jesus exchanged His righteous, holy nature for our sinful nature so that we can stand before God completely clean and pure, new creations with the old sin nature gone forever (2 Corinthians 5:17-21). God provided the perfect sacrifice for our sin, not because we deserved it or earned it, but because of His love and grace and mercy (Ephesians 2:8-9). Only those whose natures have been changed can escape the wrath of God and live in the light of His love and mercy. If we believe these things and commit our lives to following Christ by faith, we will live eternally with Him in the bliss and glory of heaven. This is good news indeed.
Biblical evangelism begins with prayer for the guidance of the Holy Spirit in witnessing, open doors of opportunity, and a clear understanding of the bad news of sin and wrath and the good news of love, grace, mercy and faith.
