Week 18 – Outreach: Facing Sin and Satan

Life is war. That’s not all it is. But it is always that. Our weakness in prayer is owing largely to our neglect of this truth. Prayer is primarily a wartime walkie-talkie for the mission of the church as it advances against the powers of darkness and unbelief.

John Piper

All authority has been given to Me in heaven and on earth. God therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age.
Matthew 28:18-20

Outreach – To Minister to the Lost


“How then shall they call upon Him in whom they have not believed? And how shall they believe in Him whom they have not heard? And how shall they hear without a preacher?” (Romans 10:14)

In Acts 1:8, Jesus tells His disciples, “And you shall receive power when the Holy Spirit comes on you and you will be My witnesses in Jerusalem, all Judea, and Samaria, and to the uttermost parts of the earth.” These four areas of outreach of the first church included Jerusalem (represents people like us), Judea (a nearby region), Samaria (people representing a different culture) and the uttermost parts of the earth. All four places serve as a model for us today.

To fulfill this word from Christ, we must get beyond our own four walls to minister Christ’s love to the world. Confining church activity to Sunday morning has been one of the best schemes of the devil. Outreach includes acts of compassion and bold evangelism.

We also see in the passage above that He seeks people of all nationalities to join His family. God’s church includes a broad diversity of people. This multinational and multiethnic presence in local churches reflects God’s purpose and heart in the earth (Revelation 5:9). When the world sees us together and loving one another, they realize it must be the grace of God (John 13:35).

Opposing Satan and Demonic Forces – Spiritual Warfare

As we reach out, we enter into the territory of the enemy. Jesus said that He came to earth to “destroy the works of the devil.” (Luke 10:19; 1 John 3:8). We continue that work. Matthew 16:15-20 reveals that we will ultimately prevail, but victory comes through conflict with the forces of darkness: Satan, his demons, and their schemes to “steal and kill and destroy” (John 10:10).

The church uses corporate prayer just as the Army uses the Air Force; ground forces need the strategic covering of the air power. We can have the greatest ideas, technologies, and strategies to reach the lost, but without serious prayer, we’ll never do all that is in the heart of God. Our battle is spiritual in nature and it must first be addressed spiritually (Ephesians 6:12).

The church is God’s mobile throne on earth, His primary institution empowered to deal with enemies and set people free. Jesus called Himself a liberator:

“The Spirit of the Lord is upon Me because He has anointed Me to preach the gospel to the poor. He has sent Me to proclaim release to the captives, and recovery of sight to the blind, to set free those who are downtrodden” (Luke 4:18, see also Mark 16:17-18; 2 Corinthians 10:3-5).

God has given us this ministry to help liberate people, regions, and nations. Jesus appointed and anointed His disciples to release people from the grip and bondages of the enemy (Matthew 12:25-29; Luke 10:19-21). This struggle against darkness will go on until the Lord returns. Therefore, we must know who our enemy is (Satan) and the weapons Christ has given us to defeat him.

Spiritual warfare is the invisible battle that occurs when the local church models the life of Jesus, prays against the works of darkness, and proclaims the kingdom of Christ. Although Satan and his fallen angels were defeated at the cross (Colossians 2:14-15), we are still assigned the task of resisting them, pushing them back, and advancing the kingdom of Christ into enemy territory.

The Lord Jesus has prepared us well for the spiritual battles we face. Several critical weapons equip us for victory in spiritual warfare:

Blood of Jesus Ephesians 2:13; Hebrews 10:19; Revelation 12:11
Name of Jesus Luke 1019; John 16:23-26; Acts 3:6,16; Philippians 2:10
Word of God Matthew 4:4; Revelation 12:11
Prayer Matthew 17:21,21:22; Acts 4:31,12:5; Colossians 4:2; James 5:16
Praise Psalm 147; Acts 16

These gifts from God to His children enable us to be more than conquerors. When facing the devil and his host of demons, we fear and infatuation. As the Psalmist said, “Through God we shall do valiantly” (Psalm 60:12). To be an overcomer, we must wield these spiritual weapons of war.

Angels give us another advantage in this warfare: “Are they not all ministering spirits, sent out to render service for the sake of those who will inherit salvation?” (Hebrews 1:14).

Angels are mysterious spiritual agents who minister on our behalf as we do ministry for the Lord (Hebrews 1:14). Although artists have often portrayed angels as plump babies, the biblical description is quite different – oftentimes dazzlingly brilliant, powerful and strong. Angels are powerful spiritual giants who surround, protect and assist us, especially in the ministry of spiritual warfare (Psalm 91:11; Daniel 12:1; Matthew 18:10; Revelation 12:7-12).

To encourage those who recoil at the thought of battling demons and demonic fortresses, Revelation 12:7-12 portrays this battle in the light of our guaranteed victory. When the Lord expelled Satan and the fallen angels from heaven, only one-third of the angels fell. Two-thirds of the angels remain are on our side. Moreover, when the battle is over and done, God’s people win!

God promises victory in spiritual warfare:

“Submit therefore to God. Resist the devil and he will flee from you.” (James 4:7)

“And they overcame him because of the blood of the lamb and the word of their testimony.” (Revelation 12:11)
