How can church leaders guard against threats?
How can church leaders prepare to defend against threats mentioned in Acts 20:29?

Recognizing the Threat Paul Describes

• “I know that after my departure, savage wolves will come in among you and will not spare the flock.” (Acts 20:29)

• Paul is speaking literally of destructive teachers who appear orthodox but tear churches apart (cf. Matthew 7:15).

• Because Scripture is accurate and sufficient, we receive this as an ongoing warning for every generation (2 Timothy 3:16-17).


Strengthening Personal Vigilance in Leaders

• Continual self-watch: “Pay close attention to yourselves and to all the flock” (Acts 20:28).

• Daily Scripture intake—leaders who feast on the Word quickly recognize poisonous food (Psalm 119:11).

• Humble dependence on the Spirit (Galatians 5:16); fleshly confidence creates blind spots.

• Accountability with fellow elders (Proverbs 27:17). Lone shepherds become easy prey.


Grounding the Congregation in Sound Doctrine

• Expository teaching through the whole counsel of God (Acts 20:27).

• Catechizing new believers in basic doctrines (Hebrews 6:1-2).

• Encouraging Berean-like testing of every message (Acts 17:11).

• Publishing clear doctrinal statements and reviewing them regularly (Titus 1:9).


Establishing Protective Structures

• Plurality of qualified elders to create a net of oversight (1 Peter 5:1-3).

• Guarded membership process—verify conversion, baptism, and confession of faith (Acts 2:41-42).

• Church discipline practiced lovingly but firmly to remove leaven before it spreads (1 Corinthians 5:6-7).

• Policies for guest speakers and teachers—no platform without examination (2 John 10).


Cultivating Discernment in the Whole Body

• Regular seminars on cults, false gospels, and contemporary errors (Jude 3-4).

• Training members to weigh teaching against Scripture, not charisma (1 Thessalonians 5:21).

• Encouraging Scripture memorization and small-group study where questions can surface safely (Colossians 3:16).


Maintaining Relational Presence with the Flock

• Shepherds smell like sheep—constant visitation and conversation help sense trouble early (John 10:14).

• Listening for doctrinal drift in casual talk, social media, and recommended books.

• Quick, gracious confrontation when confusion appears (2 Timothy 2:24-26).


Defending through Prayer and Spiritual Warfare

• Persistent intercession for wisdom, unity, and purity (Ephesians 6:18).

• Recognizing that behind wolves stands an enemy who schemes (Ephesians 6:11-12).

• Fasting seasons when threats intensify (Acts 13:2-3).


Resting under the Chief Shepherd

• Jesus promises, “I am the good shepherd. The good shepherd lays down His life for the sheep.” (John 10:11)

• Ultimate security rests in Him; leaders are under-shepherds who guard what is His (1 Peter 5:4).

• Faithful vigilance today prepares the church to meet Him unashamed tomorrow (2 Peter 3:14).
