There are three essential ingredients of effective evangelism (cf. John 17:13-20).

1. The World is our Mission Field. As believers who are in the world but not of the world, our need is to contact sinners. C. H. Spurgeon said, “Those men who keep themselves to themselves, like hermits, and live a supposed sanctified life of self-absorption, are not likely to have any influence in the world, or to do good to their fellow-creatures. You must love the people, and mix with them, if you are to be of service to them.” The danger we face is contamination by the world.
2. The Word is our Message. Our need then is for clarity and accuracy in speaking the message, and the danger is confusion or corruption of the message.
3. The Witness is the Messenger. Believers need character or integrity in order to avoid the danger of contradicting the gospel message.

There are many different obstacles to evangelism, but consider these four:

1. Intimidation: we fear evangelism (cf. 1 Cor 2:3)
2. Ignorance: we lack organized knowledge
3. Inability: we don’t know how to witness
4. Indifference: we lack motivation to tell others

Consider these six requirements for effective evangelism:

1. The Gospel Message, Rom 1:16; 10:17
2. A life of Integrity, 2 Cor 4:1-6; Phil 2:14-16; 2 Tim 2:20-26
3. Boldness, Eph 6:19-20
4. A Clear Presentation, Col 4:2-4
5. Dependence Upon God’s Power (2 Tim 2:25), sought through prayer (Acts 4:23-31) and brought by the Spirit (Acts 4:31)
6. A Compassion for the Lost, Matt 9:36-38; Jude 24-25
