LESSON 5 β UNDERSTANDING OUR SPIRITUAL ENEMIES
π 5th October 2025
π Adult Bible Text: Isaiah 14:12β17
π YAYA Bible Text: Romans 7:18β22
π§ Adult Memory Verse: Revelation 12:12 (KJV)
π§ YAYA Memory Verse: Romans 8:8 (NKJV)
πΉ Theme Overview
This week, both Adult and YAYA classes explore two powerful enemies believers must overcome in their spiritual journey:
Adult β My Enemy: Satan
YAYA β My Enemy: The Flesh
The Adult lesson focuses on the external spiritual enemy β Satan, who works to deceive, tempt, and destroy believers.
The YAYA lesson focuses on the internal enemy β the flesh, which represents the sinful nature within every human being.
Scripture teaches that the Christian life is not passive. It is a spiritual battle requiring awareness, discipline, and dependence on God.
Together, these lessons reveal an important spiritual truth:
π The believer must overcome both the enemy within (the flesh) and the enemy without (Satan).
When believers understand these realities, they begin to:
Recognize spiritual battles
Guard their hearts and thoughts
Depend on the power of God
Walk in victory over sin and temptation
π§ Victory in the Christian life requires overcoming both the flesh and the devil.
Adult:
π Revelation 12:12 (KJV)
βTherefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.β
YAYA:
π Romans 8:8 (NKJV)
βSo then, those who are in the flesh cannot please God."
Adult Bible Passage:
Isaiah 14:12β17
YAYA Bible Passage:
Romans 7:18β22

π The believer is Godβs temple, and the Holy Spirit is the divine guide within that temple.
Adult Bible Passage:
π Isaiah 14:12β17 β The Fall of Lucifer
This passage describes the downfall of Lucifer, who later became known as Satan.
Lucifer fell because of pride and rebellion against God.
In the passage we see several statements revealing his ambition and rebellion against God.
These statements show that Satanβs downfall began with self-exaltation and pride.
From the passage we learn:
Lucifer fell from heaven because of pride and rebellion against God (v12)
He desired to exalt himself above the stars of God and sit on the mount of congregation (v13)
He sought to ascend above the heights of the clouds and become like the Most High (v14)
Because of his pride, God declared that he would be brought down to the depths of the pit (v15)
Those who see his downfall will marvel at how such a powerful being was brought low (v16)
Satan caused destruction and turmoil on the earth and oppressed nations (v17)
This passage reveals that pride and rebellion were the root of Satanβs fall, showing the danger of self-exaltation against God.
π Reflection: Why is pride considered one of the greatest spiritual dangers in the life of a believer?
YAYA Bible Passage:
π Romans 7:18β22 β The Struggle With the Flesh
In this passage, the Apostle Paul describes the internal struggle between the desire to do good and the sinful nature.
From the passage we learn:
Nothing good dwells in the sinful nature of the flesh (v18)
The desire to do good may exist, but the ability to carry it out is hindered by the flesh (v18)
People often fail to do the good they intend to do (v19)
Sin operating within the flesh causes believers to act contrary to their intentions (v20)
There is a constant conflict between the desire to do good and the presence of evil within the human nature (v21)
The inner man delights in the law of God even though the flesh resists it (v22)
This passage reveals the spiritual tension believers experience between their new spiritual nature and the old sinful flesh.
π Reflection: Why do believers still struggle with sinful tendencies even after becoming Christians?
ADULT CLASS
YAYA CLASS
The "world" is a battleground and the Christian life is a warfare. The Bible clearly teaches that Satan is a real enemy of believers. He seeks to oppose Godβs work and destroy the lives of people.
We have been called to "good soldiers" of the Lord Jesus Christ and to war a a "good warfare"
π 2 Timothy 2:3
π 1 Timothy 1:18
π₯A. Satanβs Mission
Satan knows that his final judgment is certain.
However, before that day, he attempts to:
deceive people
lead them into sin
create confusion and division
discourage believers
According to the lesson, Satan uses several strategies to attack believers.
π§ B. Common Strategies of Satan
1οΈβ£ Lies and deception
The devil is described as the father of lies.
π John 8:44
He attempts to distort Godβs truth and mislead people.
2οΈβ£ Fear

π 1 Peter 5:8
3οΈβ£ Confusion
False teachings and misleading doctrines are tools used to confuse believers.

Satan uses discouragement to weaken faith.
π 1 Kings 19:4
7οΈβ£ Affliction
Sometimes sickness or hardship can become a tool of spiritual attack.
π Job 2:7
π§© C. How to Resist
The Bible teaches that believers can resist Satan and overcome his strategies by relying on God and applying spiritual discipline.
Believers can resist Satan through the following actions:
Submit to God and resist the devil β when believers submit to God and command the devil to leave, he must flee.
π James 4:7
Use the Scriptures β the Word of God is a powerful weapon against Satanβs temptations.
π Matthew 4:4β11
Look for the escape route during temptation β God always provides a way of escape from temptation.
π 1 Corinthians 10:13
Seek the truth through the Holy Spirit and the Scriptures β when Satan lies, believers should ask the Holy Spirit for guidance and search the Word.
π John 8:32; John 5:39
Promote peace and avoid disunity β believers should resolve conflicts quickly to prevent Satan from exploiting division.
π Hebrews 12:14; Romans 12:18
Overcome discouragement through spiritual activities β serve others, work diligently, listen to godly music, recount Godβs blessings, and encourage yourself in prayer.
π Ephesians 5:19; 1 Samuel 30:6
Exercise faith when afflicted β seek prayer from church elders or mature believers and trust God for healing.
π James 5:14β15
These practices help believers maintain spiritual victory over Satan.
The world is our external enemy, but believers also have another enemy within, called the flesh.
The flesh refers to the sinful nature that dwells inside every human being. It is not the physical body itself, but the inner tendency toward sin that opposes Godβs will.
π Romans 8:13
The devil often works through this sinful nature, using it as a stronghold to influence people toward sin.
π A. Understanding the Flesh
Before salvation, the flesh occupies the throne of the heart, manifesting as "self", and controlling the thoughts, desires, and actions of a person.
Even after receiving Christ, the flesh does not disappear. It continues to struggle against the new life in Christ and seeks to dominate again.
π Galatians 5:17
Therefore, believers must depend on Christ and the Holy Spirit to subdue the flesh and live in victory over sin.
The Bible teaches that the flesh manifests itself through selfish attitudes and behaviors.
Examples include:
Self-pride β placing oneself above others
π Exodus 5:2
Self-love β prioritizing personal desires above God
π Luke 12:16-20
Self-pity β constantly complaining and feeling victimized
π Exodus 16:2-3
Self-righteousness β believing oneβs own goodness is sufficient
π 1 Kings 19:14
Self-will β insisting on oneβs own way instead of Godβs will
π Judges 14:3
These attitudes reflect the influence of the sinful nature within people
π B. Victory Over the Flesh
Through Christ, believers receive the power to overcome the flesh.
The Bible teaches that God has provided victory through three important truths:
1οΈβ£ The Old Self Was Crucified
π Romans 6:6-7
Through Christ, the old sinful nature was defeated.
2οΈβ£ Believers Become New Creations
π 2 Corinthians 5:17
Salvation transforms a person into a new spiritual creation.
3οΈβ£ Christ Becomes the Believerβs Master
π John 5:30
Believers now live to do the will of God.
β C. Subduing the Flesh
Believers must actively discipline themselves to resist the flesh.
Practical steps include:
keeping the flesh crucified ()
π Galatians 5:24
making Christ the ruler of oneβs life
living by the fruit of the Spirit
π Galatians 5:22β23
How Both Classes Connect
Adult Class β The external enemy (Satan)
YAYA Class β The internal enemy (the flesh)
Together they reveal:
π The Christian life involves both internal and external battles.
π Believers must overcome both the devilβs attacks and the sinful nature within.
π Victory is possible only through Christ and the power of the Holy Spirit.
Walking in Spiritual Victory
Understanding these enemies helps believers remain spiritually alert.
π Galatians 5:16
βWalk in the Spirit, and ye shall not fulfil the lust of the flesh.β
When believers depend on God:
they resist temptation
they overcome the flesh
they defeat Satanβs strategies
π Ask Yourself:
Do I recognize the spiritual battles around me?
Am I aware of the sinful tendencies within my heart?
Do I actively resist Satanβs lies and temptations?
Am I walking daily in the power of the Holy Spirit?
Do I allow Godβs Word to guide my decisions?
A believer who understands spiritual warfare will:
stay alert in prayer
depend on Scripture
resist temptation
pursue holiness
