Every unsaved person will have windows of opportunities when he becomes most receptive to the gospel of Christ. The Devil works hard to keep people in darkness and will distract them by every means necessary (i.e., the death of a loved one, a crying child, a ringing phone, busyness, etc.). The salvation of a soul involves a spiritual battle that can only be won by the Lord’s intervention. There is a window of time when the lost are most receptive to the gospel, likewise suggesting only a window of opportunity for the saved to speak for Christ. This is the very reason the apostle Paul stressed the importance of the saints of God beseeching the Lord to open to them a door of utterance (Ephesians 6:19).
In order to be saved, a person must place his faith solely upon Christ’s death, burial, and resurrection for the means of salvation. Paul defined this central body of truth as the gospel of the grace of God (1 Corinthians 15:1-4; Acts 20:24). Though believers may tell what the Lord has done in their lives since being saved, the most important truth when witnessing involves Christ’s crucifixion, death, and resurrection from the dead. This truth, the resurrection of the Lord Jesus, became the theme of the early church. A careful study of the evangelistic messages of the early church testifies to this fact. Just as this doctrine historically served as the central truth when dealing with the lost, it should continue to be so today.
A witness is one who testifies to the certainty of an event. As such, the apostles gave witness to the resurrection of the Lord Jesus Christ. By doing so, they were declaring the resurrection to be an absolute truth. The disciples physically witnessed the fact that the Lord Jesus Christ had been put to death, but was alive and well. Although no believer today physically saw the birth, life, death, burial, or resurrection of the Lord Jesus Christ, we can and should still testify to its truthfulness. In order to offer an adequate witness of the Lord’s saving grace, an individual must first have experienced the new birth combined with the witness of God’s indwelling Spirit (1 John 5:10).
