How does God's past inspire confidence?
How does "the LORD your God has done" inspire confidence in God's promises?

Setting the Scene

Joshua 23:3: ‘You yourselves have seen everything the LORD your God has done to all these nations for your sake; it was the LORD your God who fought for you.’”


The Power of Remembering What God Has Done

• God’s past actions are tangible proof that His promises never fail (Joshua 21:45).

• Israel’s personal experience (“You yourselves have seen…”) turns abstract doctrine into lived reality.

• Remembering anchors faith in evidence, not wishful thinking (Psalm 77:11-12).


God’s Track Record Builds Present Confidence

• He fought for Israel in battles they could not win alone (Exodus 14:13-14).

• He sustained them in the wilderness for forty years (Deuteronomy 8:2-4).

• He fulfilled His word about the land despite human weakness (Nehemiah 9:7-8).

If He kept every promise then, He will keep every promise now (2 Corinthians 1:20).


From Historical Fact to Personal Assurance

• What God “has done” for His people in Scripture becomes the baseline for what He will do in your life (Romans 15:4).

• God’s nature doesn’t change; His faithfulness is constant (Malachi 3:6).

• The cross is the ultimate “has done,” proving He will freely give us all things (Romans 8:32).


Practical Ways to Let “What the LORD Has Done” Fuel Faith

1. Rehearse His deeds aloud—read passages like Psalm 136, noting each “His love endures forever.”

2. Journal answered prayers and past deliverances; revisit them when doubts surface.

3. Share testimonies with other believers; collective memory strengthens communal faith (Hebrews 10:23-25).

4. Sing songs grounded in biblical history—Israel’s victories, Christ’s resurrection—renewing hope through worship.


Living in Forward-Looking Assurance

• Because God already fought for Israel, we trust Him to fight for us (2 Chronicles 20:15).

• Because He already conquered sin and death, we trust Him with every lesser battle (1 Corinthians 15:57-58).

• Because He finished the greatest work, we are “confident of this very thing, that He who began a good work in you will perfect it” (Philippians 1:6).

The unbroken record of “everything the LORD your God has done” transforms past victories into a sure foundation for every promise still ahead.
