## Main Themes
- Holiness of God
- God is absolutely perfect in goodness, love, wisdom, power, justice, and purity.
- Biblical witnesses: Isaiah 6 (seraphim cry “holy, holy, holy”) and Revelation 4 (heavenly worship).
- Creation began with holy fellowship between God and humanity (Garden of Eden).
- Sin, Fall, and Redemption
- Adam and Eve’s disobedience broke fellowship with God; first promise of the Messiah appears (Genesis 3:15).
- God provided the first covering (animal skins), foreshadowing substitutionary atonement.
- Jesus’ death satisfies God’s justice and secures forgiveness and reconciliation.
- Salvation and New Birth
- New birth brings a changed heart, new desires, adoption as God’s children, and indwelling Holy Spirit.
- Genuine salvation must produce changed life; if salvation doesn’t change behavior, it is questionable.
- Wise Versus Unwise Living
- Wise: discern truth and apply it; live under God’s guidance.
- Unwise: rejecting God’s leading; living contrary to known truth; self-rule.
- Wisdom is a matter of choice, not age.
- The Holy Spirit: Indwelling and Filling
- Every born-again believer has the Holy Spirit dwelling within (John 14–16; 1 Cor 3:16; 6:19).
- Being "filled with the Spirit" means continual surrender and being controlled by the Spirit.
- Filling is ongoing, not a one-time event; requires daily surrender and obedience.
- Battle Between Flesh and Spirit
- Galatians 5:16–17: flesh desires oppose the Spirit; believers must choose to walk by the Spirit.
- Acts of the flesh vs. fruit of the Spirit: list of sins that disinherit vs. character produced by the Spirit.
- Walking by the Spirit prevents fulfilling sinful desires and produces Christlike character.
- Practical Christian Conduct
- Make the most of time because “the days are evil” (Ephesians 5:16).
- Be careful what you watch, read, and listen to; actively serve and love others.
- Obey governing authorities (Romans 13) and obey conscience; do not live recklessly.
- True power to live righteously comes from the Spirit (Ezekiel 36 promise).
