Giving
Romans 10:1415 (NIV) How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? 15 And how can they preach unless they are sent?
We can add another thought to this verse. How can they be sent unless someone provides financial support.
Praying
The Bible teaches that salvation is impossible except by the help of God. Even believing is impossible if God doesn’t intervene and assist us.
Matthew 19:2526 (NIV) When the disciples heard this, they were greatly astonished and asked, “Who then can be saved?” 26 Jesus looked at them and said, “With man this is impossible, but with God all things are possible.”
1 Corinthians 12:3 (NIV) Therefore I tell you that no one who is speaking by the Spirit of God says, “Jesus be cursed,” and no one can say, “Jesus is Lord,” except by the Holy Spirit.
In view of this, it is of utmost importance that we combine evangelism with prayer.
Satan is actively spoiling our efforts in evangelism.
2 Corinthians 4:4 (NIV) The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God.
1 Thessalonians 2:18 (NIV) For we wanted to come to youcertainly I, Paul, did, again and againbut Satan stopped us.
Matthew 13:19 (NIV) When anyone hears the message about the kingdom and does not understand it, the evil one comes and snatches away what was sown in his heart. This is the seed sown along the path.
Paul teaches that the world must be redeemed from the devil in order to be saved.
Acts 26:18 (NIV) to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.’
Jesus teaches the importance of binding the strong man (the demons) before stealing their possessions (souls). The fact that Jesus was talking about demons when he referred to the strong man can be seen from the preceding verse when Jesus was just talking about casting out demons.
Matthew 12:2829 (NIV) But if I drive out demons by the Spirit of God, then the kingdom of God has come upon you. 29 “Or again, how can anyone enter a strong man’s house and carry off his possessions unless he first ties up the strong man? Then he can rob his house.
Jesus’ ministry is one of releasing souls from the grip of Satan.
Luke 4:1621 (NIV) He went to Nazareth, where he had been brought up, and on the Sabbath day he went into the synagogue, as was his custom. And he stood up to read. 17 The scroll of the prophet Isaiah was handed to him. Unrolling it, he found the place where it is written: 18 “The Spirit of the Lord is on me, because he has anointed me to preach good news to the poor. He has sent me to proclaim freedom for the prisoners and recovery of sight for the blind, to release the oppressed, 19 to proclaim the year of the Lord’s favour.” 20 Then he rolled up the scroll, gave it back to the attendant and sat down. The eyes of everyone in the synagogue were fastened on him, 21 and he began by saying to them, “Today this scripture is fulfilled in your hearing.”
2 Corinthians 10:35 (NIV) For though we live in the world, we do not wage war as the world does. 4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
New testament example of a successful evangelism only after a spirit is bounded.
Acts 13:612 (NIV) They travelled through the whole island until they came to Paphos. There they met a Jewish sorcerer and false prophet named BarJesus, 7 who was an attendant of the proconsul (ie governor), Sergius Paulus. The proconsul, an intelligent man, sent for Barnabas and Saul because he wanted to hear the word of God. 8 But Elymas the sorcerer (for that is what his name means) opposed them and tried to turn the proconsul from the faith. 9 Then Saul, who was also called Paul, filled with the Holy Spirit, looked straight at Elymas and said, 10 “You are a child of the devil and an enemy of everything that is right! You are full of all kinds of deceit and trickery. Will you never stop perverting the right ways of the Lord? 11 Now the hand of the Lord is against you. You are going to be blind, and for a time you will be unable to see the light of the sun.” Immediately mist and darkness came over him, and he groped about, seeking someone to lead him by the hand. 12 When the proconsul saw what had happened, he believed, for he was amazed at the teaching about the Lord.
Spiritual warfare is only for those who have sufficiently prepared themselves by having a close relationship with God.
