How do God's acts boost faith and witness?
How can understanding God's "mighty acts" strengthen our faith and witness?

Setting the verse in context

Psalm 145 overflows with praise for God’s character and deeds. Verse 12 zeroes in on the purpose of recalling those deeds:

“to make known to the sons of men Your mighty acts and the glorious splendor of Your kingdom.” (Psalm 145:12)


Seeing the pattern of God’s mighty acts

• Creation: Genesis 1–2 – His word brings worlds into being.

• Deliverance: Exodus 14:13-31 – He splits the sea to rescue Israel.

• Provision: Joshua 3-4 – He dries the Jordan and brings the people home.

• Victory: 1 Samuel 17 – He topples Goliath through a shepherd boy.

• Redemption: Luke 23:44-24:7; Acts 2:22-24 – He raises Jesus, conquering sin and death.

• Expansion: Acts 2:41; 9:1-18 – He converts thousands and even persecutors.


Why recalling mighty acts strengthens personal faith

• Certainty: Historical, visible events anchor belief in concrete reality (Exodus 14:31).

• Perspective: God who once moved seas and stones still rules present trials (Psalm 77:11-12).

• Assurance: He finishes what He starts; past faithfulness predicts future help (Philippians 1:6).

• Awe: Knowledge of power breeds worship, and worship dispels fear (Isaiah 41:10).


Why recalling mighty acts fuels public witness

• Content for testimony: We share what God actually did, not vague feelings (Acts 4:20).

• Credibility: Tangible acts give the gospel historical weight (1 Corinthians 15:3-8).

• Boldness: Remembering divine victories emboldens speech (Acts 4:31).

• Hope for listeners: If God acted mightily then, He can act now for them (Romans 15:4).


Practical ways to keep the mighty acts fresh

1. Read narrative portions of Scripture aloud—let the events live in the room.

2. Memorize key verses describing God’s power (e.g., Psalm 106:2; Isaiah 63:12-14).

3. Record personal answers to prayer alongside biblical acts; the same hand is at work.

4. Share one concrete biblical event in every testimony you give.

5. Celebrate the church calendar moments (Passion Week, Resurrection Sunday, Pentecost) that spotlight God’s greatest deeds.

6. Teach children the stories early and often (Deuteronomy 6:6-7).


Cautions to avoid

• Treating mighty acts as fairy tales—Scripture presents them as factual history (2 Peter 1:16).

• Separating power from purpose—His acts reveal His kingdom’s splendor, not mere spectacle.

• Limiting God to past action—His arm is “not too short to save” today (Isaiah 59:1).

• Forgetting gratitude—remembered deeds should erupt in present praise (Psalm 103:1-2).


Conclusion: faith affirmed, witness ignited

When we grasp God’s mighty acts—creation, redemption, resurrection—we gain unshakable confidence and a story worth sharing. Just as David purposed “to make known” those works, so we step into each day ready to trust boldly and speak freely of the King whose power and glory have already filled the pages of history.

In what ways can we declare God's kingdom to the next generation today?
