When we evangelize, we must remember that we are engaged in spiritual warfare. Therefore, as Paul reminds the Ephesian church, we must always approach this task with the whole armor of God (Eph. 6:10–20). We must not be taken unaware by the designs of the evil one (2 Cor. 2:11). We must be strong, ever abounding in our service to Christ, knowing by whom and for whom we have been sent. 

Evangelism is part of the life and purpose of the church and of every Christian. A church that does not evangelize is not a true church. This may seem to be a hard statement, but it is true. The church is to make disciples, and discipleship begins with evangelism (Matt. 28:16–20). Our Savior has commissioned the church to be an instrument for extending His kingdom to all nations. As Paul states: “How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?” (Rom. 10:14). Here are five things we can bring remember when we think about evangelism.

1. The Holy Spirit serves as Christ’s emissary in the worldwide expansion of Christ’s kingdom.

In the last days of Jesus’ earthly ministry, He began to tell the disciples that it was necessary for the Son of Man to die and rise again. The disciples were confused and troubled. Jesus encouraged them not to be troubled. He would go away but would come again to receive them. In the meantime, He would send another Helper. In the interim between Christ’s going and returning, amid all circumstances, the Holy Spirit would be their help.

In John 16, Jesus reveals that the Holy Spirit would also equip the church for the Great Commission. The Holy Spirit would “convict the world concerning sin and righteousness and judgment” (John 16:8). The Holy Spirit would serve as Christ’s emissary in the worldwide expansion of Christ’s kingdom. As the disciples went to all nations, the Holy Spirit would bring home the truth of man’s need of salvation.

2. Sin is not something that people can escape on their own.

By the Spirit’s work, sin can be seen for what it truly is: the great malady of mankind. Sin is not just something one does or doesn’t do. Sin is a state—a fallen state of depravity, helplessness, and hopelessness. Man is not a sinner because of what he does or doesn’t do. Man is a sinner by nature. He does what he does because of who he is. Therefore, salvation is not just a change in lifestyle. Salvation is the beginning of a new creation (2 Cor. 5:17), and it is the Holy Spirit who convicts men and women of this fundamental truth.
